2.1 Solving Two-Step Equations 9/5/17

Essential Question: What kinds of problems need two operations?

To solve a two-step equation, use inverse operations. 1 - Undo adding/subtracting first 2 - Undo multiplying/dividing second Ex: 3 + 3x = 17

Example 1 (spiral): Ex: a) 3x + 7 = -2 c) 10.7 = -x – 43 b) 35 = 3 + 5x d) 𝑥 2 + 5 = -10

Student Companion p. 24, Part 1 Got it

Example 2 (spiral): Words --------------------------- Equation

Student Companion p. 24, Part 2 Got it

When you see more than one variable on the same side of the equal sign, combine like terms to help solve. Ex: 13.6n + 12n = 128

Practice 5x – 3 – 2x = 6 4x + 5 – 2x = 11 3x + 1 + 2x + 9 = 20
