1. Solving Equations with Variables on both sides
Foldable Notes

2. How to Solve an Equation
Name

3. #1 Use the Distributive Property if needed (are there parenthesis?)
2(x+2) + 2 = x (x) + 2(2) + 2 = x x = x + 12

4. #2
Get variables to one side if needed *use inverse/opposite operations Add/subtract Multiply/divide
2(x+2) + 2 = x (x) + 2(2) + 2 = x x = x x -x x = 12

5. #3 Combine like terms if needed
2(x+2) + 2 = x (x) + 2(2) + 2 = x x = x x -x x = 12 x + 6 = 12

6. 2(x+2) + 2 = x (x) + 2(2) + 2 = x x = x x -x x = 12 x + 6 = x = 6 Check: 2(6+2) + 2 = (8) + 2 = = = 18 yes! #4
Get the variable ALONE! ***always CHECK answer

7. Let’s Practice 5(n-3) = 2n – 6 5n – 15 = 2n – 6 -2n - 2n 3n – 15 = -6
3n = 9
n = 3

8. Whiteboard Practice with Partners
a + 5 = -5a + 5
5n + 34 = -2(1 – 7n)
