Question

2x/a+y/b=2

X/a-y/b=4​

Answer 1

Answer:

$\frac{2x}{a} + \frac{y}{b} = 2 \\ \\ \frac{x}{a} - \frac{y}{b } = 4$

let 1 by a b equal to p and one by b equal to q

$2px + qy = 2 \: \: \: equatinon1$

$px - qy = 4 \: \: \: equation2$

add 1 and 2

$3px = 6 \\ px = 2$

subtract 1 and 2

multiply equation 2 by 2

$2px - 2qy = 8$

$- qy = - 6$

now solve the rest by yourself

just put one by a in the place of P and one by v in the place of q and solve
