Answer:
(-2,-4)
Step-by-step explanation:
3x-2y=2
5x-5y=10
--
Multiply 3x-2y=2 by -5 to turn it into -15x+10y=-10
Mutiplu 5x-5y=10 by 2 to turn it into 10x-10y=20
--
Eliminate y
-15x+10y=-10
10x-10y=20
= -5x=10
Divide by -5
x=-2
--
Plug -2 to the first equation
3(-2)-2y=2
-6-2y=2
Move -6 to the other side by adding 6 to both sides
-2y=8
Divide by -2
y=-4
(x,y) = (-2,-4)
(-2,-4)
x=-2, y= -4
