1. Objective: Students will be able to write and solve two- step equations with one variable!

2. - 4 -4 +18 +18 4 y = 8 ::

3. 2x + 5 = -3 What is on the same side of the equal sign as the variable x ? And what mathematical operations are being done to the variable? Rule #1: ALWAYS UNDO ADDITION OR SUBTRACTION FIRST (This turns your equation into a one-step equation.) - 5 -5 2x = -8 Rule #2: Undo Multiplication or division after addition or subtraction!!!! Now you have created a one-step equation which you already know how to solve! 2 : : : X = -4

4. What is on the same side of the equal sign as the variable x ? And what mathematical operations are being done to the variable x ? - 7 -7 ::
