$- 3 - 4 \tan (x) = 1$

Step 1

Subtract $1$ from both sides of the equation.

$- 3 - 4 \tan (x) - 1 = 0$

Step 2

Subtract $1$ from $- 3$ .

$- 4 - 4 \tan (x) = 0$

Step 3

Set the argument in $\tan (x)$ equal to $\frac{π}{2} + π n$ to find where the expression is undefined.

$x = \frac{π}{2} + π n$ , for any integer $n$

Step 4

The equation is undefined where the denominator equals $0$ , the argument of a square root is less than $0$ , or the argument of a logarithm is less than or equal to $0$ .

${x | x = \frac{π}{2} + π n}$ $n$ , for any integer $n$
