Question

If x/y = 3/4, then find the value of the expression, (5x – 3y)/(7x + 2y).

Answer 1

Answer:

3/29

Explanation:

$\frac{x}{y}=\frac{3}{4}  \\x=\frac{3}{4}y \\\\therefore\\\\\frac{(5x-3y)}{(7x+2y} =\frac{(\frac{15}{4}y-3y) }{(\frac{21}{4}y + 2y) }=\frac{\frac{3}{4}y }{\frac{29}{4}y } =\frac{3}{29}$
