x - 3y = -3: multiply by -2 giving -2x + 6y = 6, but -2x + 6y = 12 so we have a problem! Misprint?
it is -4
yes
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

6y
6y = 12x+32 Divide all terms by 6: y = 2x+5 and 1/3 which is now in slope intercept form

-6y + 14 + 4y = 32-2y = 32 - 14-2y = 18y = - 9

6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
They are parallel lines.
