You can put this solution on YOUR website!
y=+-3x+%2B+5
y=+3x+-+1
______________ since left sides equal, right sides must be equal too

+-3x+%2B+5=3x+-+1...solve for x
1%2B+5=3x+%2B3x
6=6x
highlight%28x=1%29
plug x in one of equations above and solve for y
y=+-3%2A1%2B+5
y=+-3%2B+5
highlight%28y=+2%29
so, your answer is: A. 1,+2
