(6x - 5y) + (-3x - 4y) =6x - 5y - 3x - 4y =3x - 9y =3 (x - 3y)
It's the equation of a straight line with a slope of -1.5 and a y-intercept of -3.
6X - 4Y = 24 - 4Y = -6X + 24 Y = 3/2X - 6 slope(m) = 3/2 Y intercept = - 6
11x + 2y
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
If 6x + 10 = 11x , then x=2.
x=7

5x + 32 = 11x - 105x - 11x = -10 - 32-6x = -42x = 7
6x plus 4y
6x + 5x = 11x
6x - 4y
It is the same as: 6x+4y
-5x+1 = 6x -5x-6x = -1 -11x = -1 x = 1/11
The lines are parallel.
