3y +3y = 6y
3y + 4z + 12y = 3y -3y -3y ------------------------- 4z + 12y = 0 divide everything by 4 z + 3y = 0 -3y -3y z = -3y
-x+3y+6x-6y=5x-3y
The equation for 3y + 3y = -1 is 3y + 3y = -1.
5x+3y
X + 3y - 2y + 3y = X + (3-2+3)y = X + 4y
It's 5hx+10kx6y.
-3y + y = -2y
2x-11
the simplest form of 5x + 3y +2x - 6y is 7x-3y
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
