Answer:

D

Step-by-step explanation:

7a + 6 = -5(a -6)

<=> 7a + 6 = - 5a + 30

<=> 7a + 5a = 30 - 6

<=> 12a = 24

<=> a  = 2

=> Answer is D

Hope this helps!

Answer:

a=2

Step-by-step explanation:

1. distribute the -5 to (a-6): 7a + 6 = -5a + 30

2. add 5a to both sides, and subtract 6 on both sides: 12a = 24

3. divide by 12: a = 2
