Answer: x=3 y=3
Elimination method.
eliminating x and solving for y.
-2x +y=-3
-x+2y=3
-2(-x+2y=3)
2x -4y = 6
Multiply the second equation by -2 so the x’s cancel out.
-2x+y=-3
2x-4y=6
-2x and 2x cancels out
Add like terms
y-=-6
4y=-3
solve.
-3y = -9
divide by -3 on both sides and
y=3
Plug in 3 for the place of y in either either equation.
-2x+ 3= -3
solve for x.
-2x+ 3= -3
-3 -3
-2x=-6
Divide by -2
x=3
