​Combine like terms 2x+3x = 5x

​Distribute 2(2x-2) = 2x-4

​Move the variable (Inverse operations)

​​Add or Subtract (Inverse operations)

​​​Multiply or divide (Inverse operations)

Let's practice our skills together on a few examples.

Example #1: Solve this equation.

9x - 6x + 15 = -12

Think about what your first step would be here BEFORE using inverse operations.

Example #2: Solve this equation.

-2x - 10x + 12 = 18

Remember how we handle parentheses first!

Example #3: Solve this equation.

2(1 - x) + 4 = -8

Example #4: Solve this equation.

-2(x - 4) + 3x = 13

Don't lose track of where your equal sign is!

Example #5: Solve this
equation.
15 + 7x = 3 + x

How's it going so far?

Example #6: Solve this equation.

15 + 2x = 7 + x + 1
