Solve for y: 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© Algebra House
