**Solve for x; x+9=18-2x**

## Answer

**x=3**

## Explanation

x + 9 = 18 -2x

**Add 2x to both sides**

x + 9 + 2x = 18

**Add x and 2x**

3x + 9 = 18

**Move all terms not containing x to the right side of the**

**equation**

3x = 18 – 9

**Subtract 9 from 18**

3x = 9

**Divide each term in 3x = 9 by 3**

x = 3.
