Question

if x/y = 13/6 then find value of 3x + 5y/3x - 5y​

Answer 1

Answer:

$\frac{23}{3}$

Step-by-step explanation:

$\frac{x}{y} = \frac{13}{6}$

$x = 13 \: y = 6$

$\frac{3x + 5y}{3x - 5y} = \frac{3(13) + 5(6)}{3(13) - 5(6)}$

$\frac{39 + 30}{39 - 30} = \frac{69}{9} = \frac{23}{3}$

Answer 2

Step-by-step explanation:

Multiplying both sides by 3/5

We get

3x/5y =39/30

Now applying componendo dividendo property

3x+5y/3x-5y =39+30 ÷39-30

=69/9
