Answer:

x = -2
y = 3

Explanation:


-4x-2y=2\\ -4x+y=11

Subtract the two equations


-4x-2y-(-4x+y)=2-11

Remove parentheses


-4x-2y+4x-y=2-11

Cancel one variable


-2y-y=2-11

Combine like terms


-3y=2-11

Calculate the sum or difference


-3y=-9

Divide both sides of the equation by the coefficient of variable


y=(-9)/(-3)

Determine the sign for multiplication or division


y=(9)/(3)

Cross out the common factor


y=3

Substitute into one of the equations


-4x+3=11

Rearrange variables to the left side of the equation


-4x=11-3

Calculate the sum or difference


-4x=8

Divide both sides of the equation by the coefficient of variable


x=-(8)/(4)

Cross out the common factor


x=-2

The solution of the system is


x=-2\\ y=3

I hope this helps you
