What does 9a-2=12+2a​

Mathematics
1 answer:
Paraphin [41]3 years ago
4 0

Answer:

a=2

Step-by-step explanation:

Subtract 2a from both sides.

9a−2−2a=12

Combine 9a and −2a to get 7a.

7a−2=12

Add 2 to both sides.

7a=12+2

Add 12 and 2 to get 14.

7a=14

Divide both sides by 7.

a=\frac{14}{7}

Divide 14 by 7 to get 2.

a=2
