Question

5a - 9 + a = 9

Answer 1

Answer:

a = 3

Step-by-step explanation:

1) Simplify 5a - 9 + a to 6a - 9.

$6a - 9 = 9$

2) Add 9 to both sides.

$6a = 9 + 9$

3) Simplify 9 + 9 to 18.

$6a = 18$

4) Divide both sides by 6.

$a = \frac{18}{6}$

5) Simplify 18/6 to 3.

$a = 3$

Therefor, the answer is, a = 3.
