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 = -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
2x-4y=-8-2x......-2x-4y=-2x-8(-4y)/-4 | (-2x-8)/-4y=1/2x+2
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=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
Combine like terms: -2x - 4y + 5x - 7y = 3x - 11y -2x + 5x = 3x -4y + -7y = -11y
2x + 4y = 16 <=> 2x + 4y - 16 = 0 2x - 4y = 0 2x - 4y = 2x + 4y - 16 -8y = -16 y = 2 Substituting the known value for y in either of the original equations enables x to be determined. 2x + (4*2) = 16 : 2x = 16 - 8 : x2x = 8 : x = 4 2x - (4*2) = 0 : 2x - 8 = 0 : 2x = 8 : x = 4. The ordered pair satisfying both equations is (4,2)
Yes.
the system of equations 3x-6y=20 and 2x-4y =3 is?Well its inconsistent.
