2x - 4y = 8 2x = 4y + 8 x = 2y + 4

2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
2x + 4y = 16 is the same as 4y = -2x + 16 divide both sides by 4 and you get y = (-x/2) +4 3x - 2y = 6 is the same as -2y = -3x + 6 divide both sides by 2 and you get y = (-3x/2) + 3 therfore they do not have the same solution
2x+4y = -8 4y = -2x-8 y = -1/2x-2 or y = -0.5x-2
2x-4y=-8-2x......-2x-4y=-2x-8(-4y)/-4 | (-2x-8)/-4y=1/2x+2
The solution is:- x = 0 and y = 5
They are parallel lines.
Add 2x to each side: 4y = 2x Divide each side by 2: 2y = x So any two numbers where one is twice the other will be a solution.
2x - 4y = 8 2x = 4y + 8 x = 2y + 4
3
2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
2x + 4y = 16 is the same as 4y = -2x + 16 divide both sides by 4 and you get y = (-x/2) +4 3x - 2y = 6 is the same as -2y = -3x + 6 divide both sides by 2 and you get y = (-3x/2) + 3 therfore they do not have the same solution
2x-4y=4 -4y=-2x+4 y=1/2x-1 Slope is 1/2 (.5)
2x+4y = -8 4y = -2x-8 y = -1/2x-2 or y = -0.5x-2
-2x +4y = 8 4y = 2x +8 y = 1/2x +2 Therefore: the y intercept is 2 and the slope is 1/2
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
