4y+2 = 2y+6 4y-2y = 6-2 2y = 4 y = 2
26 = -6y + 6 + 2y = -4y + 6 Subtracting 6 from both sides: 20 = -4y Dividing both sides by (-4): -5 = y
6+2y=8 -6 -6 2y=2 /2 /2 y=1
(1, 1)
3x+2y=6 2y=-3x+6 y=-1.5x+3
4y+2 = 2y+6 4y-2y = 6-2 2y = 4 y = 2
26 = -6y + 6 + 2y = -4y + 6 Subtracting 6 from both sides: 20 = -4y Dividing both sides by (-4): -5 = y
x = 5 x-2y = 6 => x = 6+2y 6+2y = 5 2y = 5-6 2y = -1 y = -1/2 and x = 5 Point of intersection: (5, -1/2)
6+2y=8 -6 -6 2y=2 /2 /2 y=1
(1, 1)
2y + 3 = 3y + 9 2y - 3y = 9 - 3 or -y = 6 so y = -6
Exactly (2y + 4) .
3x+2y=6 2y=-3x+6 y=-1.5x+3
x = y+3 x+2y = 9 => x = 9-2y y+3 = 9-2y 2y+y = 9-3 3y = 6 y = 2 and x = 5
-4(7x-3y-z)-(-6)(9x-z+2)
9+2y=3 2y=-6 y=-3
If you mean: 3x+2y+6 = 0 then it is y = -1.5x-3 as a straight line equation
