Answer 2

$\huge\star\bold\red{ANSWER}$

2x-y=4 ---------(1)

x-y=1 -----------(2)

From equ-----(2)

we get, x=1+y

put above value in equ-----(1)

so, 2(1+y)-y=4

$\implies$2+2y=4

$\implies$2y=4-2

$\implies$2y=2

$\implies$y=1........ans.......

Now, put y=1 in equ-----(2)

we get , x-1=1

$\implies$x=1+1

$\implies$x=2......ans.....

Therefore,the value is$\fbox{x = 2} and </strong><strong>\</strong><strong>fbox{y = 1}$
