Start with the given equation
Combine the logs using the identity
}=10^{\log _{10} \left(5 \right)})
Raise both sides as exponents with bases of 10. This will undo the logs
Simplify
Multiply both sides by
Distribute
Subtract 5 from both sides
Subtract 5x from both sides
Combine like terms on the left side
Combine like terms on the right side
Divide both sides by -4 to isolate x
Reduce
