3. . Multiple step Equations.  When working with an equation, simplify each side of the equal sign prior to using inverse operations. Solve 3(x + 5) = 21 Distribute 3x + 15 = 21 Subtract Divide − 15 3x = 6 33 Answer x = 2 Simplify

4. . Multiple step Equations.  When working with an equation, simplify each side of the equal sign prior to using inverse operations. Solve − 13 = 20 Combine − 13 = 20 Add Divide + 13+ 13 11m = 33 11 Answer m = 3 Simplify 6m+ 5m 11m

5. . Multiple step Equations.  When working with an equation, simplify each side of the equal sign prior to using inverse operations. Solve − 23 = 20 Distribute − (r − 17 ) − r + 17 − 23 = 20 Combine − 23 = 37 − r Subtract − 37 Divide Answer − 60 =− r − 1 60 = r

6. . Multiple step Equations. Solve 17 + − 7w = 40 − 7w = 40 15 3(w + 5) Distribute Combine + 3w − 7w 32 = 40 Subtract − 32 Simplify − 4w = 8 Divide Answer w = − 2 − 4 3w 17+ 32 + = 40 − 4w

7. Check your solution 17 + − 7w = 40 3(w + 5) Original Equation Answer w = − 2 Substitute 17 + − 7(-2) = 40 3(- 2 + 5) Simplify 17 + + 14 = 40 3( 3 ) 17 + 9 + 14 = 40 Simplify 26 + 14 = 40 Simplify 40 = 40 Check ensures accuracy
