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.
(12, 1)
4x-2y = 12 -2y = -4x+12 y = 2x-6 Therefore the y intercept is -6 and the slope is 2
2x-y=4
4x+2y = 12 2y = -4x+12 y = -2x+6 So the y intercept is 6 and the slope is -2
-2x - 2y = -122x + 2y = 122y = 12 - 2xy = 6 - x
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.
If: 12 = 2y+x then y = -1/2x+6 So: y = 2x+4 and y = -1/2x+6 which means that they are perpendicular lines

-2x=2y+5 +2x -2y -2y=2x+5 /-2 y=-1/1+2.5
4x-2y = 12 -2y = -4x+12 y = 2x-6 Therefore the y intercept is -6 and the slope is 2
2x-y=4
4x+2y=24 => 2y=24-4x => y=12-2x and the slope is -2
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
4x+2y = 12 2y = -4x+12 y = -2x+6 So the y intercept is 6 and the slope is -2
The result of the equation x + 2y - 2x - y equals x simplifies to y - x.
get it to y= -2y = 1 - 2x y = x - 0.5
