Question

Whats the first inverse operation you would do for the problem 2 1/4a - 7 1/2 = 21

Answer 1

The equation is as follows

$2\frac{1}{4}a-7\frac{1}{2}=21$

The first step to clear the variable is the following.

$2\frac{1}{4}a-7\frac{1}{2}+7\frac{1}{2}=21+7\frac{1}{2}$

add 7 1/2 to both sides
