Answer:

x=5

Explanation:

Correct way:

Add 2x to 3x ( 5x )

3x-7=8

Add 7 to 8 ( 15 )

3x=15

Divide 15/3

x= 5

What was wrong:

You need to combine like terms and put the variable on the left side of the equation and then follow the steps above. You also forgot to divide.

Hope this helped, Have a Great Day!!

Answer:

x = 3, the error is that the -2x should be added.

Explanation:

The -2x should be added to the left side.

3x - 7 = -2x + 8

3x + 2x = 8 + 7

5x = 15

x =3
