Solving Equations with Variables on Both Sides

TO SOLVE EQUATIONS WITH VARIABLES ON BOTH SIDES2(x-1) + 4x = 3x + 7Simplify each side by:1. Using the distributive property2x - 2 + 4x = 3x + 72. Combining like terms6x - 2 = 3x + 7Add or Subtract both sides to isolate the variable (aka get the letter by itself)6x - 2 = 3x + 7 +2 +2 6x = 3x + 9-3x -3x3x = 9Multiply or Divide both sides to get the variable isolated3x = 9 3 3x = 9
