Question

B. Solve for x:
1/x + 1/x+5= 1/10​

Answer 1

Answer:

x=−20/49

Step-by-step explanation:

1/x+1/x+5=1/10

Simplifies to:

5x+2/x=1/10

Let's solve your equation step-by-step.

5x+2/x=1/10

Step 1: Cross-multiply.

5x+2/x=1/10

(5x+2)*(10)=1*x

50x+20=x

Step 2: Subtract x from both sides.

50x+20−x=x−x

49x+20=0

Step 3: Subtract 20 from both sides.

49x+20−20=0−20

49x=−20

Step 4: Divide both sides by 49.

49x/49=−20/49

x=−20/49

Answer 2

Given:

$\dfrac{1}{x}+\dfrac{1}{x+5}=\dfrac{1}{10}$

To find:

The value of $x$

Step-by-step explanation:

Here $\dfrac{1}{x}+\dfrac{1}{x+5}=\dfrac{1}{10}$, where $x\neq 0,-5$

$\Rightarrow \dfrac{x+5+x}{x(x+5)}=\dfrac{1}{10}$

$\Rightarrow \dfrac{2x+5}{x^{2}+5x}=\dfrac{1}{10}$

$\Rightarrow 20x+50=x^{2}+5x$

$\Rightarrow x^{2}+5x-20x-50=0$

$\Rightarrow x^{2}-15x-50=0$

Using quadratic formula, we get

$x=\dfrac{15\pm\sqrt{225+200}}{2}$

$=\dfrac{15\pm\sqrt{425}}{2}$

$=\dfrac{15\pm 5\sqrt{17}}{2}$

Final answer: $x=\dfrac{15\pm 5\sqrt{17}}{2}$

The required solution is

$\quad\quad \boxed{x=\dfrac{15\pm 5\sqrt{17}}{2}}$
