5. 5.
6. 6. Solve . Then check your solution.<br />Check:<br /> h – 12 = -27<br />-15 – 12 = -27<br /> -27 <br />= -27<br />Example 2-1a<br />
7. 7. Solve . Then check your solution.<br />k + 63 – 63 = 92 - 63<br />Check <br /> k + 63 = 92<br /> 29 + 63 = 92<br /> 92 = 92 <br />Example 2-2a<br />
8. 8. Solve . Then check your solution.<br />a – 24 + 24 = 16 + 24<br />a = 40<br />Check:<br />a – 24 = 16<br />40 – 24 = 16<br />16 = 16 <br />
9. 9. Solve . Then check your solution.<br />t + 22 – 22 = -39 – 22 <br /> t = -61<br />Check:<br /> t + 22 = -39<br /> -61 + 22 = -39<br /> -39 = -39<br />Example 2-2b<br />
10. 10. Solve<br />·3<br />·3<br />·5<br />·5<br />y =<br />Example 2-4a<br />
