Add 9y to each side of the equation:

2x/5 - 9y + 9y = 6 + 9y

Cancel the 9y's on the left side to get:

2x/5 = 6 + 9y

Multiply each side of the equation by 5:

5(2x/5) = 5(6 + 9y)

Cancel the 5's on the left side to get

2x = 5(6 + 9y)

Divide each side of the equation by 2:

2x/2 = 5/2(6 + 9y)

Cancel the 2's on the left side to get:

x =

**5/2(6 + 9y)**
