3-3 Solving Multistep Equations Objective: To solve equations using add., subt., mult., and division.

Examples 1 – 3 (watch & listen) 5n + 6 = -4 -6 -6 5n = -10 5 5 n = -2 17 = 7y + 87 -9 -9 (5) (5)

Examples 4 – 6 (do with me)

Example 7 – 9 (with a partner)

Solve.

Recap with a partner… 1) Explain to your partner how to solve a multi-step equation. 2) Explain how to solve the following equation:

Homework Pg. 160 # 17 – 33 odd Check your answers in the back of the book.

Math Lab Review today’s lesson Homework Please finish worksheets from last week: Why did the ant run across the cracker box? What did the Spanish Farmer say to his chicken?

solve two-step equations. Objective The student will be able to: Designed by Skip Tyler, Varina High School

To solve two-step equations, undo the operations by working backwards. Example: Ask yourself, 1. What is the first thing we are doing to x? 2. What is the second thing? Recall the order of operations as you answer these questions. Dividing by 2 Subtracting 3 To undo these steps, do the opposite operations in opposite order.

1) Solve 2x - 1 = -3 + 1 + 1 2x = -2 2 2 x = -1 2(-1) - 1 = -3 -2 – 1 = -3 1. Draw “the river” 2. Add 1 to both sides 3. Simplify 4. Divide both sides by 2 5. Simplify 6. Check your answer

+ 4 + 4 3 · · 3 x = 36 12 – 4 = 8 2) Solve 1. Draw “the river” 2. Add 4 to both sides 3. Simplify 4. Clear the fraction -Multiply both sides by 3 5. Simplify 6. Check your answer
