Elimination using addition and subtraction. -4x+4y=-20 -2x+4y=-2

goldfiish [28.3K]

I would subtract the 2nd from the first one

so -4x - -2x = -2x

4y - 4y = 0

-20 - -2 = -18

-2x = -18

now I would divide that by -2 to get the value for x

so no we have x = 9

now you just have to substitute that into one of the equations and simplify to get y

-2 X 9 + 4y = -2

-18 + 4y = -2

4y =16

y = 4
