Question

Solve the following equation :
5/X+1 -2/y-1 = 1/2
10/X+1 -2/y-1 =5/2

Answer 1

Step-by-step explanation:

1)5/x+1/1-2/y-1/1=1/2

=(5+x÷x)-(2-y÷y)=1/2

CROSS MULTIPLICATION(LCM)

=(5y+xy)-(2x-xy)÷xy

=5y-2x÷xy=1/2

(CROSS MULTIPLICATION )

=2(5y-2x)÷2xy =xy

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

=2x^2y^2+4x-10y=0

****************************

2)10+x÷x-2-y÷y=5/2

=10y+xy-2x-xy÷xy=5/2

=10y-2x÷xy=5/2

=20y-4x÷xy=5xy

=20y-4x=5x^2y^2

=5x^2y^2+4x-20y
