9/5/17

2. Essential Question: What kinds of problems need two operations?

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

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

8. 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

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