x + 2x + 6x = 9x
6x-52 = 4x+40 6x-4x = 40+52 2x = 92 Answer: x = 46
2x + 6x + 4x = 12x
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
5x + x - 6x + 2x = 2x
6x + 9 + 2x = 8x + 9
-2x + 11 + 6x = 4x + 11
6x
2x + 9 = 6x + 1 9 - 1 = 6x - 2x 8 = 4x x = 2
6X + 3 = 2X + 19Subtract 3 from each side:6X = 2X +16Subtract 2X:4X = 16Divide by 4X = 4
6x - 9 + 2x + 1 = 8x -8
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
