Question

solve 10+apon x+y +2 apon x-y =4; 15 apon x+y -5apon x-y =-2​

Answer 1

Step-by-step explanation:

10/x+y +2/x-y =4_________(1)

15/x+y -5/x-y =-2_________(2)

now solve both the equation simultaneously

on solving equation no. 1 we get

[10(x-y) +2(x+y)]/(x+y)(x-y) =4

10x-10y+2x+2y/x^2-y^2 =4

12x-8y÷x^2-y^2 =4

12x-8y =4(x^2-y^2)_____

now solve these two euations
