5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
Because (x plus 3x) is 4x, and (-5 + 11) is 6.
x+4x+5=5x+5
4x + 17 = x + 2 4x - x = 2 - 17 3x = -15 x = -5
4x + 5 < 5x + 3 5 < x + 3 x > 2
4x =20x=20/4x=5
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
-4x + 5 + 3x + 6 = -x + 11
Because (x plus 3x) is 4x, and (-5 + 11) is 6.
If its x+4x+5 then: 5x+5
x+4x+5=5x+5
4x + 17 = x + 2 4x - x = 2 - 17 3x = -15 x = -5
4x + 5 < 5x + 3 5 < x + 3 x > 2
4x+5 = -9 4x = -9-5 4x = -14 x = -3.5
4x + 5(x - 2) +124x + 5x - 10 + 129x + 2
If: 3x+5 = 4x+1 Then: x = 4
4x3 + 16x2 - 180x = 4x(x2 + 4x - 45) = 4x(x + 9)(x - 5)
