6y-y3 = 3
6y + 8 = 32 6y + 8 - 8 = 32 - 8 6y = 24 6y/6 = 24/6 y = 4
6y(1) & 6y(3) The answer is 6y

25x2 - 36y2 = ( 5x + 6y ) ( 5x - 6y )
6y + 11 = 23 6y = 23 - 11 6y = 12 y = 12/6 y = 2.
-6y + 5 = -67y=12-6y = -72-y = -12y = 12
3x + 6y = 363x - 6y = 0 add both equations6x = 36x = 63x - 6y = 03(6) - 6y = 018 - 6y = 018 = 6y3 = yThe solution point is (6, 3).

6y-y3 = 3
6y-8y = -2
17yquared-6y = 11
3x + 6y + 6x = 9x + 6y which can be factorised as 3(3x +2y)
