ANSWER


x=3

Step-by-step explanation

We want to solve the equation using a common base. Since the bases on both sides of the equation are equal, the exponents are also equal.

This implies that:


3x-7=5-x

Collect like terms and simplify:


\begin{gathered} 3x+x=5+7 \\ 4x=12 \\ x=(12)/(4) \\ x=3 \end{gathered}

That is the solution.
