5) What value of x makes this equation true (Show your work) ?

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

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
