anonymous

Best ResponseYou've already chosen the best response.0Combine like terms first, so 3x  1x is 2x, solve from there, 2x + 2 = 12. subtract 2 from both sides, you have 2x = 10.

Best ResponseYou've already chosen the best response.0You want base value of x, so divide both sides by 2.

Best ResponseYou've already chosen the best response.0Okay, you know how to distribute right?

anonymous

Best ResponseYou've already chosen the best response.0Well Distribute your 4 to each number in the parentheses, give me your new equation, I'll do my best to teach you from there.

Best ResponseYou've already chosen the best response.0No, you wouldn't add 4 to the +1, you'd multiply, and 4 x 1 is 4.

anonymous

Best ResponseYou've already chosen the best response.0But either way, we now have 4x + 4 + 8 = 24

anonymous

Best ResponseYou've already chosen the best response.0When distributing, you're multiplying by the outside term,

anonymous

Best ResponseYou've already chosen the best response.0So you just take your numbers one at a time, 4 x 1x and 4 x 1

Best ResponseYou've already chosen the best response.0but it will give you 16x = 24

anonymous

Best ResponseYou've already chosen the best response.0No, you don't add them up, this is probably the part that confuses you.

Best ResponseYou've already chosen the best response.0So, we need to do the opposite of each other term.

Best ResponseYou've already chosen the best response.04x + 4 + 8 = 24, we need to get rid of the 8, so we can Subtract 8 from both sides.

Best ResponseYou've already chosen the best response.04x + 4 + (8  8) = 24  8

anonymous

Best ResponseYou've already chosen the best response.0No, the x is the thing we want to keep, we get rid of everything elseon it's side.

Best ResponseYou've already chosen the best response.0Let's make this a step easier, 4x + 12 = 24.

anonymous

Best ResponseYou've already chosen the best response.0If you want to get rid of 12, so you just have 4x what would you do?

anonymous

Best ResponseYou've already chosen the best response.0And remember what ever you do to one side, you do to the other.

anonymous

Best ResponseYou've already chosen the best response.0I don't think so, if you added it would make the 12 go up. we want it to go down to 0.

anonymous

Best ResponseYou've already chosen the best response.0That's actually incorrect.

anonymous

Best ResponseYou've already chosen the best response.0Yes, what would you subtract though?

anonymous

Best ResponseYou've already chosen the best response.0If you want 12 to be 0, and remember you do it to both sides.

Best ResponseYou've already chosen the best response.04x  12 = 24 24/8 = 3 the answer is 3

anonymous

Best ResponseYou've already chosen the best response.09c+4=23 9c=234 9c=27 9c/9= 27/9 remain the C devide it by 9 c= 3

Best ResponseYou've already chosen the best response.0You should of subtracted 12, from both sides which got you too 4x = 12

anonymous

Best ResponseYou've already chosen the best response.0Then divide both sides by 4.

anonymous

Best ResponseYou've already chosen the best response.0So you would get x=3

anonymous

Best ResponseYou've already chosen the best response.0That's not always going to happen, you don't want to do that... You already had +12. you would do 12 to make it 0.
