$\tan (x - π) = \tan (x)$

Step 1

For the two functions to be equal, the arguments of each must be equal.

$x - π = x$

Step 2

Move all terms containing $x$ to the left side of the equation.

Step 2.2.1

Subtract $x$ from $x$ .

$0 - π = 0$

Step 2.2.2

Subtract $π$ from $0$ .

$- π = 0$

Step 3

Multiply $- 1$ by $3.14159265$ .

$- 3.14159265 = 0$

Step 4

Since $- 3.14159265 \neq 0$ , there are no solutions.
