Answer:

y = 5

x = 8

Step-by-step explanation:

x - y = 3

this is first equation.3x - 2y = 4

this is second equation .

>multiply the 1st eq. {x-y =3} by 3

so we get

3x - 3y = 9

let this equation be 3rd.

then substitute equation 2nd and 3rd.

3x - 3y = 9

3x - 2y = 4

sign change.. \\

we get

y = 5

then put the value of y in any equation you will get you value of x.
