Best ResponseYou've already chosen the best response.1show me what you did with this 9(4x4)=3(12x+7)

Best ResponseYou've already chosen the best response.1do this only 9(4x4) I want to see your steps.

Best ResponseYou've already chosen the best response.09(4x4)=3(12x+7) 36x4=36x+7 36x4+4=36x+7+4 36x36x=11 ok here is where I get lost because there is no x so is the answer real or empty

godorovg

Best ResponseYou've already chosen the best response.1no .. try again hint we want X alone.

tootie149

Best ResponseYou've already chosen the best response.0there is no x because 36x36x is nothing

tootie149

Best ResponseYou've already chosen the best response.09*4=36 and 3*12 is 36

godorovg

Best ResponseYou've already chosen the best response.1okay first off there are not two 36x36x wrong. 9(4x4) doesn't = 36x36x no

Best ResponseYou've already chosen the best response.1don't feel that way, sometimes i make little mistakes as well. we all learn in different ways.

Best ResponseYou've already chosen the best response.0now for the other side i got 36x+21

Best ResponseYou've already chosen the best response.1hey one thing is slow down and do the steps, don't skip ahead just some friendly advice

Best ResponseYou've already chosen the best response.0tootie you are correct with your solution the expansion is 36x  36 = 36x + 21 subtract 36x from both sides and you get 36 = 21 no solution

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.1yes that is 36x+21 now again how do we get x alone?

campbell_st

Best ResponseYou've already chosen the best response.0its basically saying y = 36x  36 and y = 36x + 21 the lines are parallel ... so no intersection....

Best ResponseYou've already chosen the best response.1campbell yes are right about 36x36x I wasn't at that point yet..

Best ResponseYou've already chosen the best response.0well tootie has actually has a correct piece of maths above... sorry...

tootie149

Best ResponseYou've already chosen the best response.0so the solution set is empty. right?

Best ResponseYou've already chosen the best response.0correct... just practise expanding terms in brackets...

Best ResponseYou've already chosen the best response.0the expansion of the pronumeral was correct... its just the constant term you need to be aware of

Best ResponseYou've already chosen the best response.1oh no trouble at all..

tiffanymak1996

Best ResponseYou've already chosen the best response.0in this case if there is no x, then the set is empty, if it's all real number, all real number would work with the equation.

Best ResponseYou've already chosen the best response.0tiffanymak could you give me an example of what you mean when it comes to real numbers

godorovg

Best ResponseYou've already chosen the best response.1real numbers are 1,2,3 ,5 and so on

tootie149

Best ResponseYou've already chosen the best response.0still lost when it comes to real numbers.

tiffanymak1996

Best ResponseYou've already chosen the best response.0real numbers are like all kinds of number, rational, irrational, integer etc. just not complex number.

tiffanymak1996

Best ResponseYou've already chosen the best response.0say: integer:  [infinite], 8, 7, 6,5...0,1,2,3,4,5....., [infinite] these are real no.s
