Answer:
X= 2,Y= 2
Step-by-step explanation:
2x-y= 2 consider it as equation 1
3y-4x= - 2 => - 4x+3y= - 2 => - (-4x+3y= - 2)
4x-3y= 2 consider it as equation 2
2x-y =2 =>equation 1 multiply with 2(2x-y=2) => subtract 2 equations
4x-2y= 4
4x-3y=2

(-) (+) (-)

Y = 2
Substitute y value in equation 1
2x-y= 2 => 2x-2=2 => 2x = 2+2 => 2x= 4=> x= 4/2
X=2
X=2, Y=2
