One-fifthx – two-thirdsy = 30, when y = 15?

200

Explanation:

First, you would plug in 15 for y so the equation would be

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

Then you would multiply -2/3 and 15 and get -10.  Now your equation should look like this:

1/5x - 10 = 30

You would then add 10 on each side and your equation should look like

1/5x = 40

by multiplying the denominator (5) on each side, your variable x will equal 200 because 40 x 5 = 200
