2x = 11x + 4 Subtract 11x from both sides: -9x = 4 Divide both sides by -9: x = 4/(-9) = -0.444...
no
9x+6 = 6x+15 9x-6x = 15-6 3x = 9 x = 3
no
9x + 91 is already simplified because there is nothing that is on the other side of the "equals" sign.
2x + 6 + 9x = 39 11x + 6 = 39 11x = 39 - 6 11x = 33 x = 3
x + 20 + 10x = 20 + 9x 11x + 20 = 20 + 9x Subtract 20 from both sides: 11x = 9x Subtract 9x from both sides: 2x = 0 Divide both sides by 2: x = 0
9x+18 = 180 9x = 180-18 9x = 162 x = 18
9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
11x + 5y
2x + 9x simplified would be 11x
14 + 2x + 9x - 6 - 11x 14 - 6 + 2x + 9x - 11x The x values cancel themselves out, leaving just the number value The answer is therefore 8.
2x = 11x + 4 Subtract 11x from both sides: -9x = 4 Divide both sides by -9: x = 4/(-9) = -0.444...
-11x + 13
(9x + 7)(x - 2)
It is possible.
