Answer 1

You have the equation:

1/5 x - 2/3 y = 30

if y = 15, you have:

1/5 x - 2/3 (15) = 30

1/5 x - 10 = 30

solve the previous equation for x, as follow:

1/5 x - 10 = 30 subtract 10 both sides

1/5 x = 30 + 10

1/5 x = 40 multiply by 5 both sides

x = 20(5)

x = 200

Hence, the solution for x is x = 200
