Question

the difference of two numbers is 0.77 . if the greater number is increased 5 times the difference becomes 77

Answer 1

Explanation:

x - y = 0.77

5x - y = 77

let's subtract the first from the second equation :

5x - y = 77

- x - y = 0.77

---------------------

4x 0 = 76.23

x = 76.23/4 = 19.0575

x - y = 0.77

y = x - 0.77 = 19.0575 - 0.77 = 18.2875
