-6 + 4x + (9-2x) = -6 + 4x + 9 - 2x = [ 3 + 2x ]
4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
2x + 6x + 4x = 12x
4x-1=2x+1
8x-2x+4x=10x
2x + 4x - x = 5x
2x + 4x + 3 = 6x + 3
4x plus 3 plus 2x is equivalent to expression 6x plus 3.
2x + 3y + 4x + 9y = 2x + 4x + 3y + 9y = 6x + 12y which can be simplified to 6(x + 2y)
4x 2
6x
2x + 33 = 4x + 11 -11 -11 2x + 22 = 4x -2x -2x 22 = 4x Divide each side by 4 x = 5.5
