Answer 1

Answer: In step 4, -9 is added to 9 to make 0.
This is an example of the inverse property of addition. -9 and 9 are inverses, and when inverses are added together they cancel out and equal 0.

A = 36

$(4)/(6) = (24)/(a)$

Next cross multiply;

4a = 6 × 24

4a = 144

a = 144 ÷ 4 (did the inverse operation)

a = 36
