Answer:

a = 15/8

Explanation:

You want the solution to the two-step linear equation ...

-1/2 +1/3a = 1/8

Solution

When an equation involves fractions, it is often useful to clear fractions by multiplying the equation by their least common denominator. Here, that means we want to multiply the equation by 24.

-12 +8a = 3 . . . . . . multiply the given equation by 24

8a = 15 . . . . . . . . add 12

a = 15/8 . . . . . . divide by the coefficient of the variable

The solution is a=15/8 or 1 7/8.
