Question

Solve for a.
ба -15=72
A.27
B.12
C.9 1/2
D.14 1/2

Answer 1

a= 14.5

Explanation:

6a - 15= 72

You should move the able variables to the opposite side so it would be easier for you.

= 6a = 72+15

= 6a = 87

Then you want to isolate (a) so you should divide 6 on each sides to get (a) alone.

`(6 a)/(6) = (87)/(6)`

The 6 cancels out with the 6 so now we have :

a = 14.5
