Step-by-step explanation:

Multiply both sides of the equation by the denominator "5".

This will make a the subject of the formula because all the other terms will be on the other side of the equation.

Answer:

A in (-oo:+oo)

A/5 = 7/15 // - 7/15

A/5-(7/15) = 0

A/5-7/15 = 0

1/5*A-7/15 = 0 // + 7/15

1/5*A = 7/15 // : 1/5

A = 7/15/1/5

A = 7/3

A = 7/3
