Question

How do I solve 9a-7=110

Answer 1

You'll need to isolate 9a on the left side of this equation
Please add 7 to both sides of the eqn, obtaining 9a = 117.

Solve for a by dividing both sides by 9:  a = 117/9 = 13 (answer)

Answer 2

$9a-7=110$ 

$9a=110+7$ 

$9a=117$ 

$a= \dfrac{117}{9}$ 

$a=13$
