4 Steps for Solving Two-Step Equations Solve for any Addition or Subtraction on the variable side of equation by “undoing” the operation from both sides of the equation.Solve any Multiplication or Division from variable side of equation by “undoing” the operation from both sides of the equation.Steps for Solving Two-Step Equations
6 Helpful Hints?Identify what operations are on the variable side. (Add, Sub, Mult, Div)“Undo” the operation by using opposite operations.Whatever you do to one side, you must do to the other side to keep equation balanced.
7 To solve two-step equations, undo the operations by working backwards. Recall the order of operations as you answer these questions.1)Ask yourself,What is the first thing we are doing to x?What is the second thing?To undo these steps, do the opposite operations in opposite order.
8 Solve the equations by doing the opposite operations in the opposite order. Add 3 to both sidesSimplifyClear the fraction -Multiply both sides by 2Check your answer
9 2) Solve 2x - 1 = -3 Add 1 to both sides Simplify Divide both sides by 2Check your answer
10 3) Solve Add 4 to both sides Simplify Clear the fraction -Multiply both sides by 3Check your answer
