3x + 6y + 6x = 9x + 6y which can be factorised as 3(3x +2y)
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
If: 6y-3x = 18 Then: y = 0.5x+3 which is in slope-intercept form
3x-6y=12; subtract 12 & add 6y to both sides 3x-12=6y; divide by 6 (1/2)x-2=y; re-write y=(1/2)x-2 slope intercept form

(y - 3)(x + 2y)
3x + 6y + 6x = 9x + 6y which can be factorised as 3(3x +2y)
3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
5x2y = 3x - 6y 5x2y + 6y = 3x y(5x2 + 6) = 3x y = (3x)/(5x2 + 6) This is a rational function.
3x - 6y = 9Subtract 3x from each side:-6y = -3x + 9Multiply each side by -1 :6y = 3x - 9Divide each side by 6:y = 0.5x - 1.5
6y-3x-9(1-1)=6y-3x-9(0)=6y-3x-0=6y-3xOnly like terms can be simplified. A like term has the same variables, X and Y are different variables. 6y-3x cannot be simplified because they are not like terms.
y = -1x/2 3x + 6y = 0 -3x -3x __________ 6y = 0 - 3x --- -------- 6 6 y= -3x/6 y= -1x/2
If the equation is 6y - 3x - 2 = 0 6y - 3x - 2 = 0 6y = 3x + 2 y = (1/2)x + 2 The slope is 1/2. If the equation is 6y = -3x - 2 y = -(1/2)x - 2 The slope is -1/2.
3x + 6y = 363x - 6y = 0 add both equations6x = 36x = 63x - 6y = 03(6) - 6y = 018 - 6y = 018 = 6y3 = yThe solution point is (6, 3).
(3x - y)(x - 3y) (6y - 11)(6y + 11)
