2x = 11x + 4
Subtract 11x from both sides: -9x = 4
Divide both sides by -9: x = 4/(-9) = -0.444...
180=11x+9x. 180 = 20x. 18=2x. 9=x.
11x(2x - 1) = 0 so either 11x = 0 or x = ½
2x+32 = 1 2x = 1-32 2x = -31 x = -15.5
22+2x = 37+6+x 2x-x = 37+6-22 x = 21
(3x+1)(2x+4)
2x + 9x simplified would be 11x
2x + 6 + 9x = 39 11x + 6 = 39 11x = 39 - 6 11x = 33 x = 3
2x2 + 11x + 15 = (x + 3)(2x + 5).
180=11x+9x. 180 = 20x. 18=2x. 9=x.
2x - 13 x = 24 -11x = 24 -11x/-11 = 24/-11 x = -2 2/11
13x + 15 = 11x - 5 2x = -20 x = -10
2x+a=p 2x=p-a x=.5p-.5a

3x + y + 1 = 0y = - 3x - 12x - 3y + 8 = 03y - 2x - 8 = 03y = 2x + 8y = 2x/3 + 8/3-3x - 1 = 2x/3 + 8/3-9x - 3 = 2x + 8-11x = 11x = -1y = -3x - 1 = 3 - 1 = 2The graphs intersect at the point (-1, 2).

2x2 + 11x + 12 = 2x2 + 3x + 8x + 12 = x*(2x + 3) + 4*(2x + 3) = (2x + 3)*(x + 4)
