2y y - 1

---- = -------

9 3

A.) 1/3

B.) 3/5

C.) 4/9

D.) 5/4

E.) 3

When two fractions are equal, that is a "proportion". To solve, just cross-multiply.

2y y - 1

---- = -------

9 3

9(y - 1) = 2y(3) {cross-multiplied}

9y - 9 = 6y {used distributive property}

-9 = -3y {subtracted 9y from both sides}

y = 3 {divided both sides by -3}

**E.) 3**
