ONE STEP EQUATIONS MULTIPLICATION DIVISION 6 2 3

ONE STEP EQUATIONS: MULTIPLICATION & DIVISION 6. 2. 3. 1 Represent real world or mathematical situation using equations and inequalities involving variables and positive rational numbers. 6. 2. 3. 2 Solve equations involving positive rational numbers using number sense, properties of arithmetic and the idea of maintaining equality on both sides of the equation.

12. 4 NOTES ONE STEP EQUATIONS: MULTIPLY & DIVIDE The goal of solving an equation is to find the value of the variable. § We do this by isolating the variable on one side of the equation using Inverse Operations! § Inverse operations “undo” each other! Ø Inverse of multiplication DIVISION Ø Inverse of division MULTIPLICATION

I can… • Solve one step equations by using the inverse operations for multiplying and dividing Self Assessment 5 - I can do it without help & teach others. 4 - I can do this with no help, but I don’t know if I can explain it. 3 - I can do this with a little help. 2 - I can do this with a lot of help! 1 - I don’t have a clue.

• To solve an multiplication equation, divide the same number from each side. • The goal is for the variable to be by itself on one side. POOF 5 x= 20 5 5 x=4 Che ck: 5 x__4 _=2 0

• To solve an multiplication equation, divide the same number from each side. • The goal is for the variable to be by itself on one side. POOF 65 = 5 q 5 5 13 = q Che ck: 6 5=5 x __13 _

Your Turn SOLVE THE EQUATION, THEN CHECK THE SOLUTION Solve Check 1. 15 = 6 n 2. 5 1. 15 = 6 x ____ 2. 3 m = 15 5 2. 3 x ____ = 15
