Answer:
x=6

Subtract 2x from both sides


8x-72-2x=2x-36-2x\\6x-72=-36

Add 72 to both sides


6x-72+72=-36+72\\6x=36

Divide both sides by 6


6x/6=36/6\\x=6

Answer:

x=6

Explanation:

first thing first you always need to get x alone and since you have an X on both side we need to move one of them to the same side as the other one.

8x-72=2x-36

add 72 on both sides ( the opposite of subtracting is adding)

8x=2x-36+72

8x=2x+36

then we subtract 2x on both sides to get X alone

8x-2x=36

6x=36

then we divide 36 by 6 to get our answer for x

X= 6

and that's your answer, hope this helped
