Answer: x=-3, y=-8
Step-by-step explanation:
you will leave the first equation alone for now
the second, we will subtract 2y from both sides
5x-2y=1
now you system is
4x-y=-4
5x-2y=1
we will multiply the first equation with -2
-8x+2y=8
5x-2y=1
add both equations, we get -8x+5x=9, -3x=9,
x=-3
we will replace x with -3 in any equation, lets use 4x-y=-4,
-12-y= -4, -y=12-4, -y=8, y=-8
