# Equations

## Exam Prep Study Notes (Things to remember)

 Equation A mathematical statement of an equality containing one or more variables One step equations These are equations that take only one step to isolate the variable. Example x + 5 = 2. When you subtract both sides by 5 you get the answer. ...... .........

### Tips

 Solving equations The trick to solve equations is to isolate the variable. Simplify each side of the equation first  apply the distributive property as needed combine like terms where possible  move the variable to one side of the equation perform the inverse operations of addition or subtraction perform the inverse operations of multiplication or division as needed confirm the answer by substituting the value of the variable into the equation. Example: =22a + 170 = 10a - 44 Add 22a to both sides to get  170 = 32a - 44 Now add 44 to both sides to get 214 = 32a  Now divide both sides by 32 to get the value of a a = 214/32 = 6.6875  Now substitute the value of a into 170 = 32a - 44 to check the validity of the answer. ........ ..........
