Answer 2

Yes, it's -12, is there a reason why you're unsure about it?

Answer 3

i dont know how to solve it

Answer 4

here lets do it step by step ok?

Answer 5

we want to get x moved to one side of the equation

Answer 6

do you know how to do that?

Answer 7

4(x-3) = 7x + 24
4x - 12 = 7x +24
4x - 7x = 24 + 12
-3x = 36
3x = -36
x = -12

Answer 8

check:
4[(-12)-3)] = 7(-12) +24
4[(-15)]= (-84) +(24)
4(-15) = -60
and (-84)+ (24) = -60

Answer 9

This is solved: x = -12
