the system of equations 3x-6y=20 and 2x-4y =3 is?Well its inconsistent.

3x - 4y = 8Solve for x:3x = 4y + 8x = 4/3y + 8/3Solve for y:-4y = -3x + 8y = 3/4x - 2
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
3x-4y = 8 -4y = -3x+8 y = 3/4x-2 or y = 0.75x-2 which is the equivalent in slope intercept form
the system of equations 3x-6y=20 and 2x-4y =3 is?Well its inconsistent.
(1, 1)
x = 1, y = -1
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
x = 1 and y = -1 (1, -1)

They are parallel because the slope has the same value in both equations.
3x - 3 = 2x + 6 3x = 2x + 9 x = 9
1
2x+3=3x-3 2x-3x=-3-3 -x=-6 x=6
3x + 4y = 7 2x + y = 3 4*eqn (2) - eqn(1): 5x = 5 so that x = 1 Substitute this value in eqn (2): 2 + y = 3 so y = 1 So the ordered pair is (1,1)
3x+4 = 2x-3 3x-2x = -3-4 x = -7
