Answer:

x = 8

Step-by-step explanation:

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

12x - 28 = 36 +4x

12x - 4x = 36 + 28

8x = 64

x = 8

To control we put x = 8 in the formula 4(3x-7) = 36 +4x

4(3*8 -7) = 36 + 4*8

4(24-7) = 36 +32

4* 17 = 36 +32

68 = 68  So this means x = 8 is correct

the answer= 8 and the work goes as the following

you multiply the 4 outside the brackets by the numbers inside so it becomes:
12x-28=36+4x
and then you bring the like terms together
12x-4x=28+36
12-4=8 so
8x=64
and then you divide by 8 so
x=64 divided by 8
x=8
