5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2

6*3-6*2-12x v v 18 - 12-12x v v 6-24x -6 -6 something like that..
72
2x2 - 72 would be factored into (2x - 12)(x + 6) or (2x + 12)(x - 6) To double check, multiply each pair: (2x - 12)(x + 6) = 2x2 + 12x - 12x - 72 = 2x2 - 72 (2x + 12)(x - 6) = 2x2 - 12x + 12 x - 72 = 2x2 - 72
x = -6
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
This is not an inequality. This is an equation.12x+7=43 12x=36 x=3
12x = 11x - 5, subtract both sides by 11x x = -5
4x2 = -12x, divide both sides by 4x: x = -3
its just a line, there are many answers that would work -12x-6y=0 -12x=6y x=-y/2 y=-2x
12x - 6 = 10x +2 12x - 10x = 2 + 6 2x = 8 x = 4

6*3-6*2-12x v v 18 - 12-12x v v 6-24x -6 -6 something like that..
12x + 17 = 7 Subtract 17 from both sides: 12x = -10 Divide both sides by 12: x = -10/12 = -5/6
12x-14w+103y+72+16-56+0-65+2w+0 original = 12x-14w+2w+103y+72+16-56+0-65+0 group = 12x-12w+103y-33 answer
2x - 3y = -1 Eq.1y = -4x + 24 Eq.2Put the value of Eq.2 on Eq.22x - 3(-4x + 24 ) = -12x + 12x -72 = -114x -72 = -114x = 72-114x = 71x= 71/14 .............. X = 5.07
