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

If jon had $4.00 then takes away $2.25, then he should have $1.75 left. $4.00 - $2.25 = $1.75 hope this ; )
