$- 2 = 2^{x + 1} - 2$

Step 1

Rewrite the equation as $2^{x + 1} - 2 = - 2$ .

$2^{x + 1} - 2 = - 2$

Step 2

Move all terms not containing $x$ to the right side of the equation.

Step 2.1

Add $2$ to both sides of the equation.

$2^{x + 1} = - 2 + 2$

Step 2.2

Add $- 2$ and $2$ .

$2^{x + 1} = 0$

Step 3

Take the natural logarithm of both sides of the equation to remove the variable from the exponent.

$\ln (2^{x + 1}) = \ln (0)$

Step 4

The equation cannot be solved because $\ln (0)$ is undefined.

Undefined

Step 5

There is no solution for $2^{x + 1} = 0$
