Best ResponseYou've already chosen the best response.0I'm assuming you mean 5+3(1+2(2x3)) = 6(x+5)

sandra

Best ResponseYou've already chosen the best response.0this is another case where you need to distribute

Best ResponseYou've already chosen the best response.0start with the right side, what is 6(x+5) ?

sandra

Best ResponseYou've already chosen the best response.0ok now start from the inside out on the left hand side

Best ResponseYou've already chosen the best response.0do u always start with the right side

sandra

Best ResponseYou've already chosen the best response.0well, I think generally start from inside out

sandra

Best ResponseYou've already chosen the best response.0as in innermost thing that needs to be expanded

sandra

Best ResponseYou've already chosen the best response.0ok great, so to recap, so far we have: 5 + 3(1 + 4x  6) = 6x + 30

sandra

Best ResponseYou've already chosen the best response.0so to make it easier on yourself, how about combing like terms in the parens, so what is (1+4x  6) ?

anonymous

Best ResponseYou've already chosen the best response.05x6 or do u break that down further

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0well, that's not correct

sandra

Best ResponseYou've already chosen the best response.0you can't combine 1 and 4x, since you don't know what 4x

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0but you can combine 1 and 6

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0if it had been (1x +4x 6) you would have been correct, since the 1 and 4 are both x's

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0right so the middle is now 5 + 4x, or 4x  5

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0so now you have : 5 + 3(4x  5) = 6x + 30

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0so can you combine anything on the left side?

anonymous

Best ResponseYou've already chosen the best response.05 and 15 which is 10

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0yep =), so now what do you have?

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0so now the basic rule of algebra, and equations/equalities in general  you can perform any operation to both sides of an equation and still have the equatoin be true (satisfied)

sandra

Best ResponseYou've already chosen the best response.0the reason that's powerful is because it allows you to eventually get x all by itself

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0so let's say you wanted to get 12x by itself on the left hand side

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0what could you add to both sides to make that happen?

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0yep, and what do you get if you add 10 to both sides

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0exactly. ok , so remember, when you're solving for a variable (in this case x), the idea is to get all of that variable to one side, and then eventually just one instance of that variable by itself (x)

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0so what could you subtract from both sides, to get all of the x's in one place?

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0exactly, and then what you get?

anonymous

Best ResponseYou've already chosen the best response.06x=40 then i divided by 6 both sides

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0yeah, or you could write it as a fraction

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0and that can be reduced if you divide both top and bottom by 2

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0so now that you think x = 20/3

anonymous

Best ResponseYou've already chosen the best response.0thank u so much i think im getting it sum what lol

sandra

Best ResponseYou've already chosen the best response.0you stick it back into the original equation (or just use 6.666666 to check in your calculator)

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0and if the equation is true, then you know you got it right

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0so for these types of problems, try expanding everything out first

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0and then just keep doing the same operations on both sides until you conveniently get all the x's (or whatever you're solving for) in one place

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0and then just get the value for one x by dividing

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0after a while, you'll start seeing some shortcuts if they're there

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0for example, if you had 3(x+3) = 12

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0you wouldn't *have* to expand first

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0you could just divide both sides by 3

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0and then subtract 3 from both sides to get x=1

sandra
 5 years ago
Best ResponseYou've already chosen the best response.0but seeing that will come with practice

anonymous

Best ResponseYou've already chosen the best response.0oh ok thanks a bunch !!!!
