Answer:

a=2

Step-by-step explanation:

First, we need to add 1/2 over, but we need a common denominator

To get a common denominator of 4, multiply 1/2 by 2/2

1/2*2/2=2/4

5/8a-1/2=3/4

5/8a-2/4=3/4

5/8a=5/4

Then, multiply by the reciprocal of 5/8 to isolate a

8/5(5/8a)=5/4(8/5)

a=40/20

a=2

Hope this helps!
