2. Solving One Step Equations with Division Example 1: y = 4 5 y = 4 5 1 y = 4 5 1 5(4) = 1(y) 20 = 1y y = 20 Cross multiply Original equation Check: y = 4 5 20 = 4 5 4 = 4 Original equation Substitute your answer to check to see if the two sides are equal. Note: * To solve equations with division, put the whole number over on and cross multiply. * Remember, what you do to one side of an equation, you must do to the other. Put the whole number (4) over one. Solution

3. Solving One Step Equations with Division Check: 12 = z 4 12 = 48 4 12 = 12 Original equation Substitute your answer to check to see if the two sides are equal. Note: * To solve equations with division, put the whole number over on and cross multiply. * Remember, what you do to one side of an equation, you must do to the other. Example 2: 12 = z 4 12 = z 1 4 12 = z 1 4 1(z) = 12(4) 1z = 48 z = 48 Cross multiply Original equation Solution Put the whole number (12) over one.
