Question

-3x + 7= 28
what does x equal

Answer 1

x = -7

Explanation:

`-3x+7=8` subtract 7 on both sides

`-3x=21` divide -3 into both sides

`x=-7`

To check

-3(-7) = 21 + 7=28

Answer 2

-3x+7=28
1st step move the seven to the other side of the equal sign and change it from positive to negative like this
-3x=21
Step 2 divide 21 by -3 and the answer will be -7
