Answer 2

Answer:

The question is a bit confusing as the proper brackets are not used so let’s consider two possible cases as follows

Case 1:

[math]\frac{x+1}{x}=3[/math]

[math]x+1=3x[/math]

[math]2x=1[/math]

[math]x=\frac12[/math]

Case 2:

[math]x+\frac{1}{x}=3[/math]

[math]\frac{x^2+1}{x}=3[/math]

[math]x^2-3x+1=0[/math]

[math]x=\frac{-(-3)\pm\sqrt{(-3)^2-4(1)(1)}}{2\cdot 1}[/math]

[math]x=\frac{3\pm\sqrt5}{2}[/math]
