Answer:
a= 14.5
Step-by-step 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.
[tex] \frac{6 a}{6} = \frac{87}{6} [/tex]
The 6 cancels out with the 6 so now we have :
a = 14.5
