Question

A fraction becomes 2/5 when 2 is added to the numerator and 5 subtracted from the dinominator.represent this situation as a linear equation in two variables.also find its two solution

Answer 1

Let the fraction be x/y.
Given
(x+2)/(y-5) = 2/5

5x+10= 2y- 10
5x-2y+20=0

Answer 2

The linear equation is
5x+2y+20=0

The solutions of x,y are
x=0,y=10
