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
Answer:
63=x*y
Step-by-step explanation:*
y = 7 x=1. so 9 will muiltiply 7 until there is 9 7s then you got the answer
Answer:
y=1.2x-3
