$\ln (5 - 2 x) = - 3$

Step 1

For logarithmic equations, $\log_{b} (x) = y$ is equivalent to $b^{y} = x$ such that $x > 0$ , $b > 0$ , and $b \neq 1$ . In this case, $b = e$ , $x = 5 - 2 x$ , and $y = - 3$ .

$b = e$

$x = 5 - 2 x$

$y = - 3$

Step 2

Substitute the values of $b$ , $x$ , and $y$ into the equation $b^{y} = x$ .

$e^{- 3} = 5 - 2 x$
