Find Where Undefined/Discontinuous 3/x+2=3/(4x)+17/8

$\frac{3}{x} + 2 = \frac{3}{4 x} + \frac{17}{8}$

Step 1

Move all the expressions to the left side of the equation.

Subtract $\frac{3}{4 x}$ from both sides of the equation.

$\frac{3}{x} + 2 - \frac{3}{4 x} = \frac{17}{8}$

Subtract $\frac{17}{8}$ from both sides of the equation.

$\frac{3}{x} + 2 - \frac{3}{4 x} - \frac{17}{8} = 0$

Step 2

Simplify $\frac{3}{x} + 2 - \frac{3}{4 x} - \frac{17}{8}$ .

To write $\frac{3}{x}$ as a fraction with a common denominator, multiply by $\frac{4}{4}$ .

$\frac{3}{x} \cdot \frac{4}{4} - \frac{3}{4 x} + 2 - \frac{17}{8} = 0$

Write each expression with a common denominator of $x \cdot 4$ , by multiplying each by an appropriate factor of $1$ .

Multiply $\frac{3}{x}$ by $\frac{4}{4}$ .

$\frac{3 \cdot 4}{x \cdot 4} - \frac{3}{4 x} + 2 - \frac{17}{8} = 0$

Move $4$ to the left of $x$ .

$\frac{3 \cdot 4}{4 x} - \frac{3}{4 x} + 2 - \frac{17}{8} = 0$

Combine the numerators over the common denominator.

$\frac{3 \cdot 4 - 3}{4 x} + 2 - \frac{17}{8} = 0$

Simplify the numerator.

Multiply $3$ by $4$ .

$\frac{12 - 3}{4 x} + 2 - \frac{17}{8} = 0$

Subtract $3$ from $12$ .

$\frac{9}{4 x} + 2 - \frac{17}{8} = 0$

To write $2$ as a fraction with a common denominator, multiply by $\frac{8}{8}$ .

$\frac{9}{4 x} + 2 \cdot \frac{8}{8} - \frac{17}{8} = 0$

Combine $2$ and $\frac{8}{8}$ .

$\frac{9}{4 x} + \frac{2 \cdot 8}{8} - \frac{17}{8} = 0$

Combine the numerators over the common denominator.

$\frac{9}{4 x} + \frac{2 \cdot 8 - 17}{8} = 0$

Simplify the numerator.

Multiply $2$ by $8$ .

$\frac{9}{4 x} + \frac{16 - 17}{8} = 0$

Subtract $17$ from $16$ .

$\frac{9}{4 x} + \frac{- 1}{8} = 0$

Move the negative in front of the fraction.

$\frac{9}{4 x} - \frac{1}{8} = 0$

Step 3

Set the denominator in $\frac{9}{4 x}$ equal to $0$ to find where the expression is undefined.

$4 x = 0$

Step 4

Divide each term in $4 x = 0$ by $4$ and simplify.

Divide each term in $4 x = 0$ by $4$ .

$\frac{4 x}{4} = \frac{0}{4}$

Simplify the left side.

Cancel the common factor of $4$ .

Cancel the common factor.

$\frac{4 x}{4} = \frac{0}{4}$

Divide $x$ by $1$ .

$x = \frac{0}{4}$

Simplify the right side.

Divide $0$ by $4$ .

$x = 0$

Step 5

Find Where Undefined/Discontinuous 3/x+2=3/(4x)+17/8
