Work Step by Step

(3x-5) / 2y If x is 7, and y is 8, plug them in. Split this into two fractions. 3x / 2y + -5/2y Change the sign. 3x/2y- 5/2y Plug 7 in for X. 3(7)/2y - 5/(2y) Now plug in 8 for Y. 3(7)/2(8) - 5 / 2(8) Simplify. 21 - 1 * 5 / 16 Simplify the numerator. You get 16. 16/16 reduces to 1/1 so the answer is 1.
