2x-6y = 9 Rearranging: 6y = 2x - 9 Divide through by 6: y = (1/3)x - 3/2
-2x-6y=6 can be written as -6y=2x+6 or y=-2/6x-1 This tells us the y intercept is 1. You can also plug in x=0 to find the y intercept. So when you replace x with 0 in -2x-6y=6 you have -6y=6 so y=-1 again Now to find the x intercept, let y be 0 so 0=2x+6 or -6=2x which tells us x=-6/2 or -3 and this is the y intercept.
the system of equations 3x-6y=20 and 2x-4y =3 is?Well its inconsistent.
It is (2x +y + 3)*(2x - y - 3).
20x2 + 22xy + 6y2 = 20x2 + 10xy + 12xy + 6y2 = 10x(2x + y) + 6y(2x + y) = (2x + y)(10x + 6y) = 2(2x + y)(5x + 3y)
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
2x-6y = 20 -6y = -2x+20 y = 1/3x-20/6 The slope is 1/3
-2x - 6y = -8 2x + 6y = 8 6y = -2x + 8 y = -2/6 x + 8/6 y = -1/3 x + 4/3

2x-6y = 9 Rearranging: 6y = 2x - 9 Divide through by 6: y = (1/3)x - 3/2
5x -6y=-30 5x-6y=30 (2x+3y) (2x-3y)=30 4x+6y=30 4x=30 x=30/4
x - 3y = -3: multiply by -2 giving -2x + 6y = 6, but -2x + 6y = 12 so we have a problem! Misprint?
the simplest form of 5x + 3y +2x - 6y is 7x-3y
2x + 6y = 6Subtract 2x from each side:6y = -2x + 6Divide each side by 6:y = -1/3 x + 1The graph is a straight line, with a slope of [ -1/3 ], and intersecting the y-axis at the point [ y = 1 ].
Since y = 2, 2x + 6y is the same as 2x + 12. Because 2x + 12 = 22, 2x = 10. If 2 Xes are equal to ten, then 1 X is equal to 5.
Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24 ?Improved Answer:2x+6y = 243x-2x = 24 => x =24Substitute the value of x into the top equation to find the value of y:48+6y = 246y = 24-486y = -24y = -4So: x = 24 and y = -4
If you mean: 2x-9y = 14 and x-6y = 7 then it works out x = 7 and y = 0
