Solving Two-Step Equations Standard: MCC8EE7ab Objective: Solve equations using two steps

Objective - To solve equations involving two steps. Hard wayEasy way 3x + 4 = 16 - Undo Multiplication or Division first - Undo Addition or Subtraction first 3x + 4 = 16

Hard wayEasy way 3x + 4 = x = x = 3 x = 12 3 x = x = x = 4 - Undo Mult./ Div. first - Undo Add./ Subt. first

1) Goal:Isolate the variable on one side of the equation. ISOLATE 2) Always perform the same operation to both sides of an equation. BALANCE 3) To undo an operation, perform its opposite operation to both sides of the equation. INVERSE OPERATION

Solve the following equations.
