Question

Please can anyone help me?

Answer 1

Answer: As per question,

x/y=7/4

x=7y/4

Putting this Value in x+y=88

11y/4=88

y=32

x=56

x-y=56-32=24

Step-by-step explanation:

Answer 2

Answer: 24

Step-by-step explanation:

x:y = 7:4 => x/y = 7/4 => x = (7/4)y         ...1

Given,

x + y = 88

We know,

x = (7/4)y          (from 1)

=> x + y = (7/4)y + y = 88            (substituting (7/4)y instead of x)

(11/4)y = 88

y = 88 X 4/11 = 32

As     x + y = 88  

        x + 32 = 88

        x = 88 - 32  = 56

x - y = 56 - 32 = 24  (where x = 56 and y = 32)
