A/4 - 5/6 = - 1/2

What's a

A = 4/3 because if u add 5/6 to - 1/2 it would equal 1/3 and then you would multiply 1/3 by 4 and that would equal 4/3 which is the answer. You can check your work by turning 4/3 into 8/6 and subtract it by 5/6 which equals 3/6 and simplifying it to 1/2

4/3/4-5/6=-1/2

a=4/3 or 1.3 recurring
