How to solve multi step equations with variables on both sides and parentheses?

First expand the parentheses

Then rearrange the variables so they are on one side of the equation

Then rearrange the constant terms so they are on the other side

Example-

7x - 3 (x - 2) = x + 3

7x - 3x + 6 = x + 3

-x - x

7x - 4x + 6 = 3

-6 - 6

7x - 4x = - 3

3x = - 3

x = - 1
