Question

3/x+1/x-4/x=-2+3+1. ​

Answer 1

⟶ $\frac{3}{x}$ + $\frac{1}{x}$ - $\frac{4}{x}$ = -2 + 3 + 1

$= > \frac{3}{x} + \frac{1}{x} - \frac{4}{x} = 2$

Now, multiply on both sides with "x"

$= > ( \frac{3}{x} + \frac{1}{x} - \frac{4}{x} ) \times x = 2x$

$= > (\frac{3x}{x} + \frac{1x}{x} - \frac{4}{x} ) \times x = 2x$

$= > (4 - \frac{4}{x} ) \times x = 2x$

$= > 4 + ( \frac{ - 4x}{x} ) = 2x$

$= > 4 - 4 = 2x$

$= > 0 = 2x$

• 2x = 0
• x = $\frac{0}{2}$

⟶ x = 0
