6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
2x/3y
2x + 3y + 4x + 9y = 2x + 4x + 3y + 9y = 6x + 12y which can be simplified to 6(x + 2y)

2x + 3y - x + 5y combine the like terms 2x - x + 3y +5y simple arithmetic x + 8y
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
2x-11
2x/3y
4(2x + 3y)(2x + 3y)
2x + 3y = 12 x = 1.45, so 2 * 1.45 + 3y = 12 2.9 + 3y = 12 3y = 12 - 2.9 = 9.1 y = 9.1/3 = 3.0333... or 91/30 or 3 1/30.
the simplest form of 5x + 3y +2x - 6y is 7x-3y
2x + 3y + 4x + 9y = 2x + 4x + 3y + 9y = 6x + 12y which can be simplified to 6(x + 2y)
Y=4-(2x/3)
2x plus 3y
2x + 4y - 5x + 3y = 7y - 3x
it is 26-3y=12
