Answer:
The answer to your question is x = 7.168
Step-by-step explanation:
Equation
9 = 13
Process
1.- Get logarithms in both sides of the equation
(x - 6) log 9 = log 13
2.- Pass log 9 to the right side
x - 6 = log 13 / log 9
3.- Solve for x
x = 6 + log 13 / log 9
4.- Simplification
x = 6 + 1.1139 / 0.9542
x = 6 + 1.168
x = 7.168
