4x+3y = 12 3y = -4x+12 y = -4/3x+4
If: 4x+(-12) = 8 then 4x = 20 and x = 5
It is: 12x2-7x-12 equals (4x+3)(3x-4) when factored
(4x2 - 13x - 12)/(4x+ 3) = (4x + 3)(x - 4)/(4x + 3) = (4x + 3)(x - 4)/(4x + 3) = x - 4 :)
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
If: 4x-4 = 12 Then: x = 4
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
-4x + 8 = -4 -4x + 8 - 8 = -4 -8 -4x = -12 -4x/-4 = -12/-4 x = 3
-4x-4 equals -16. Add 4 to both sides; -4x equals -12. Divide both sides by -4; x equals 3.
4x+3y = 12 3y = -4x+12 y = -4/3x+4
4[x+3]=4x+12 4x+12=4x+12 it's open.
4x - 12 = 4Divide each side by 4:x - 3 = 1Add 3 to each side:x = 4
8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
it is 4
8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3
