9(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

9(4x4) is 36x36
 2 years ago

godorovg Group TitleBest ResponseYou've already chosen the best response.1
yes so what is x now?
 2 years ago

godorovg Group TitleBest ResponseYou've already chosen the best response.1
no .. try again hint we want X alone.
 2 years ago

tootie149 Group TitleBest ResponseYou've already chosen the best response.0
there is no x because 36x36x is nothing
 2 years ago

tootie149 Group TitleBest ResponseYou've already chosen the best response.0
9*4=36 and 3*12 is 36
 2 years ago

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

now for the other side i got 36x+21

hey one thing is slow down and do the steps, don't skip ahead just some friendly advice
 2 years ago

campbell_st Group TitleBest ResponseYou've already chosen the best response.0
tootie 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
 2 years ago

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

tootie149 Group TitleBest ResponseYou've already chosen the best response.0
subtract 36x36x
 2 years ago

campbell_st Group TitleBest ResponseYou've already chosen the best response.0
its basically saying y = 36x  36 and y = 36x + 21 the lines are parallel ... so no intersection....
 2 years ago

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

well tootie has actually has a correct piece of maths above... sorry...

in 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.
