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 = 20 2y = -4x+20 y = -2x+10
4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)
8x+2y=4x=-y/4+0.5y=-4x+2
4x + 2y = 6 (first equation x 2) 4x + 2y = 6 (second equation rearranged) No unique answer exists

2y = 4x + 4y = 2x + 2
4x+2y=24 => 2y=24-4x => y=12-2x and the slope is -2
4x+2y = 20 2y = -4x+20 y = -2x+10
4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)
8x+2y=4x=-y/4+0.5y=-4x+2
-4x-2y = 3 -2y = 4x+3 y = -2x-1.5 which is the equation of a straight line
what is the slope of the line that has the equation 4x+2y=12?
4x + 2y = 6 (first equation x 2) 4x + 2y = 6 (second equation rearranged) No unique answer exists
-2
4x+2y-8=0 2y=8-4x y=4-2x slope= -2
4x+2y = 6 2y = -4x+6 y = -2x+3 Slope = -2
