4x-2y = 2
4x2 - 4x + 2xy - 2y = 4x(x - 1) + 2y(x - 1) = (x - 1)(4x + 2y) = 2(x - 1)(2x + y)
4x+2y = 20 2y = -4x+20 y = -2x+10
4x-2y = 3 -2y = -4x+3 y = 2x-1.5 in slope intercept form
you have to solve for the variable for example. 4x + 2y = 8. you would solve for y. so you subtract the 4x and you do the same to both sides and you get 2y = -4x + 8. you then divide everything by 2 to get y by itself and you end up with y = -2x + 4
4x+2y-8=0 2y=8-4x y=4-2x slope= -2
4x + 2y = -8 → 2y = -4x - 8 → y = -2x - 4
-4x=2y-16 +16 +16 (-4x+16)=(2y) /2 /2 y=-2x+8
4x-2y = 2
2y = 4x - 16 5y = 4x + 8 Subtract the first equation from the second: 3y = 24 so that y = 8 Substitute this into the first equation: 16 = 4x - 16 ie 32 = 4x so that x = 8 So the solution is (8, 8)
4x2 - 4x + 2xy - 2y = 4x(x - 1) + 2y(x - 1) (4x + 2y)(x - 1).
4x-2y+3x+2y When simplified: 7x
Add 4x to each side: 2y = 4x + 8Divide each side by 2: y = 2x + 4
4x2 - 4x + 2xy - 2y = 4x(x - 1) + 2y(x - 1) = (x - 1)(4x + 2y) = 2(x - 1)(2x + y)
4x+2y=24 => 2y=24-4x => y=12-2x and the slope is -2
4x+2y = 20 2y = -4x+20 y = -2x+10
(4x)(2y) would be factored as such: 4x = 2 • 2 • x 2y = 2 • y 2(2x)(y)
