Question 679985: need answer to ...y=6x+7 and 3x-y=2 the possible answers are A)(-3,-11) B) (-2, -8)C)(-1,1)
Answer by ReadingBoosters(3246) (Show Source): You can put this solution on YOUR website!
y = 6x + 7
3x-y=2 rearranged as y = 3x-2
...
Set the equations equal and solve for x
6x+7=3x-2
6x-3x=-2-7
3x=-9
x=-3
...
Plug in x into either equation and solve for y
y = 6(-3) + 7 = -18 + 7 = -11
...
(-3, -11) or choice
