Question

Solve equartions by cross multiplication method.

$2x-y=6,x-y=2$

Answer 1

$2x-y-6=0$ .......(1)

$x-y-2=0$ ......(2)

We know, according to cross-multiplication method,

$\frac{x}{2-6}=\frac{y}{-6+4}=\frac{1}{-2+1}$

$\frac{x}{-4}=\frac{y}{-2}=\frac{1}{-1}$

On equating first and third expression, we get

$x=4$

and, on equating second and third expression, we get,

$y=2$

Therefore, the solution is $x=4$ and $y=2$.
