9-70.

Find the value of the variable that makes each equation true.

1. $5a - 3 = 17$

Problem 9-9 is very similar to this one. Go back and look at the work done for that problem, if you are having trouble.

$a = 4$

1. $2x +1 = -9$

Again, this is similar to problem 9-9. Model your solution after the one presented in that problem.
