4x-y=2, thereforey=4x-2sub y into 3x+2y=6...3x+8x-4=611x=10x=10/11
2y = 4x + 4y = 2x + 2
4x+2y = 20 2y = -4x+20 y = -2x+10
4x+2y=24 => 2y=24-4x => y=12-2x and the slope is -2
4x + 2y = 6 (first equation x 2) 4x + 2y = 6 (second equation rearranged) No unique answer exists
4x-2y = 3 -2y = -4x+3 y = 2x-1.5 in slope intercept form
-4x-2y = 3 -2y = 4x+3 y = -2x-1.5 which is the equation of a straight line
8x+2y=4x=-y/4+0.5y=-4x+2
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.
4x+2y = 6 2y = -4x+6 y = -2x+3 Slope = -2
4x-2y = 5 -2y = -4x+5 y = 2x-2.5 The slope is 2 and the y intercept is -2.5
