Method One

You could divide by 5 right away.

20/5 = - 3 + x

4 = - 3 + x Add 3 to both sides.

4 + 3 = x

x = 7

Method Two.

You could remove the brackets. This is slightly longer, but some questions can only be solved that way.

20 = 5(-3) + 5x

20 = -15 + 5x Add 15 to both sides

20 + 15 = 5x

35 = 5x Divide by 5

35/5 = x

7 = x
