Question

X:Y= 5:3 and X+Y=56

Work out the value of x-y please help and explain

Answer 1

Answer:

Given X:Y=5:3 and X+Y=56------------1

X=5Y/3----------2

substituting above value of X in the equation 1 we get:

5Y/3+Y=56

(5Y+3Y)/3=56

8Y/3=56

Y/3=7

Y=21

subsituting the value of Y in equation 2 we get:

X=5x21/3

  =35

Hence X=35 and Y=21

_________________________

$\frac{x}{y}=\frac{5}{3}$

x = $\frac{5y}{3}$

Put x in given eqñ .

$\frac{5y}{3} + y = 56$

$\frac{8y}{3}=56$

y = 21

Put y in this eqñ

x + 21 = 56

x = 35

To find :

x - y

Substitute values

→ 35 - 21

→ 14

It is your answer
