Writing and Solving Linear Equations These are the topics that will be on your test: Section 1 - Writing Equations by Looking at Tables Section 2 - Write and Solve One-Step Linear Equations Section 3 - Write and Solve Multi-Step Linear Equations Section 4 - Write and Solve Linear Equations with x on Both Sides Section 5 - Write and Solve Linear Equations with Two Different Variables Estimated Date of Test: October 14th

4. Undo addition or subtraction 5 steps to follow when Solving Equations (isolating x) 1. 1. Distribute 2. 3. 4. Undo addition or subtraction 5. Undo multiplication or division

1. Distribute 5 steps to follow when Solving Equations (isolating x) Look for parenthesis Multiply -5(x – 9) = -5x + 45

Distribute Big Topic: Writing and Solving Linear Equations VOCABULARY Little Topic: Write and Solve Multi-Step Linear Equations VOCABULARY TERM TEACHER WORDS STUDENT WORDS OR EXAMPLE Distribute 9(6 – x) = ? 54 – 9x -3(x + 1) = ? -3x – 3 -2(x – 4) = ? -2x + 8 To multiply the # outside the parentheses by EVERYTHING inside the parentheses

YOU TRY Simplify. 1) 2) 3) 4)

- 8 - 8 4x 1 4 4 x Ex #1 THEN Undo addition and subtraction THEN DISTRIBUTE AND TWO-STEP EQUATIONS Sometimes you’ll see equations like this: Always DISTRIBUTE first THEN - 8 - 8 Undo addition and subtraction 4x 1 4 4 THEN Undo multiplication and division x GOAL: to get x by itself

+28 +28 7x 59 7 7 x Always DISTRIBUTE first Ex #2 DISTRIBUTE AND TWO-STEP EQUATIONS Sometimes you’ll see equations like this: Always DISTRIBUTE first +28 +28 THEN Undo addition and subtraction 7x 59 7 7 THEN Undo multiplication and division x GOAL: to get x by itself

YOU TRY

2(x + 3) = 10 5(h – 4) = 8 9 = -6(x – 2) -2(3 – d) = 4
