ANSWER :

x = 3

EXPLANATION :

From the problem, we have the equation :


\log_7(5x+12)=\log_7(3x+18)

Since we have two logarithms both having the same base of 7, we can equate it by :


\begin{gathered} \operatorname{\log}_(7)(5x+12)=\operatorname{\log}_(7)(3x+18) \\ 5x+12=3x+18 \end{gathered}

Solve for the value of x :


\begin{gathered} 5x+12=3x+18 \\ 5x-3x=18-12 \\ 2x=6 \\ x=(6)/(2) \\ x=3 \end{gathered}
