4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
Both of them are equations!The solution is (x, y) = (2, 1).
what is the slope of the line that has the equation 4x+2y=12?
2x+y=-12-4x-2y=30 x=-y/2+30, you plug this into -12-4x-2y=30 and get -12+2y-120-2y=30 which gives 2y-2y=162. This is not possible, so the equation is unsolvable.
They are straight lines.
x = -8, y = 10
