Question

Solve the logarithmic equation by writing in exponential form or by

graphing.
log (5-2x) = 0

Answer 1

Hello,

Explanation:

`log(5-2x)=0\\\\\ \Longleftrightarrow\ 10^(log(5-2x))=10^0\\\\\\\Longleftrightarrow\ 5-2x=1\\\\\Longleftrightarrow\ 2x=5-1\\\\\\\Longleftrightarrow\ x=(4)/(2)\\\\\\\Longleftrightarrow\ \boxed{x=2}\\`
