Find the Excluded Values (x+2)/(7x+3)

$\frac{x + 2}{7 x + 3}$

Step 1

Set the denominator in $\frac{x + 2}{7 x + 3}$ equal to $0$ to find where the expression is undefined.

$7 x + 3 = 0$

Step 2

Solve for $x$ .

Subtract $3$ from both sides of the equation.

$7 x = - 3$

Divide each term in $7 x = - 3$ by $7$ and simplify.

Divide each term in $7 x = - 3$ by $7$ .

$\frac{7 x}{7} = \frac{- 3}{7}$

Simplify the left side.

Cancel the common factor of $7$ .

Cancel the common factor.

$\frac{7 x}{7} = \frac{- 3}{7}$

Divide $x$ by $1$ .

$x = \frac{- 3}{7}$

Simplify the right side.

Move the negative in front of the fraction.

$x = - \frac{3}{7}$
