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!
Answer: option D
Step-by-step explanation:
X+8=-2
x= -2-8 (you should make x the subject so you switch the +8 to the other
