Question

. Difference between two number is 5. Four times of greater number is equal to five times the smaller number. Find the number. *

Answer 1

Answer:

X=25 Y=20

Step-by-step explanation:

Let X be the greater number

Let Y be the smaller number

Difference between two number is 5

X - Y = 5

Four times of greater number is equal to five times the smaller number

4X = 5Y

4X - 5Y = 0

So till now we get two equations

   X - Y = 5

4X - 5Y = 0

Multiply the equation ( X - Y = 5) by -4 =

- 4X + 4Y = - 20

 4X - 5Y  =    0

Add both the equations

By adding we get

-Y = -20

Y= 20      

X = 25
