If: 2x = x+5 Then: x = 5
2x-3 = x+5 2x-x = 8 x = 8

x^3=2x+5 x^3-2x-5=0 Graph the equation or use a calculator. x= 2.09455148
The factors of 5 are 1 and 5. 12 = 2 x 5 + 2 x 1, therefore: 4x2 +12x +5 = (2x + 1)(2x + 5)
x + 2x + 5 = x +19 3x + 5 = x +19 3x - x = 19 - 5 2x = 14 x = 7
X should be zeroas:X + 5 = 2X + 5so, 2X - X = 0 or X = 0
2x+2=x+5 x=3
2x+5+x-1=3x+4
X=27
If: 2x = x+5 Then: x = 5
If: x+1+2x = 1x+5 Then: x = 2
2x-3 = x+5 2x-x = 8 x = 8
2x+5+x-1=3x+4
(x + 1)(2x + 5)
(x + 4) + (x + 5) = 2x + 9
2x - 6 = x + 5 Isolate x. 2x - x = 6 + 5 x = 11
