You are a quality assurance analyst checking the calibration of a manufacturing sensor. The sensor's response curve requires solving the logarithmic equation $\log_3(4x + 3) = 3$ to find the correct threshold $x$. Recalling the mathematical procedure for solving this type of equation, what is the correct first step to rewrite the equation in exponential form?

A logistics coordinator uses logarithmic equations to model delivery times and inventory thresholds. Match each equation from the model with its corresponding first step or final solution.

A quality control technician is using a logarithmic scale to measure the durability of a new polymer coating. The durability factor $x$ is determined by solving the equation $\log_3(4x + 3) = 3$. Arrange the steps in the correct order to calculate the value of $x$.

An HVAC technician is calculating the airflow requirements for a new facility using the natural logarithmic equation $\ln e^{4x} = 4$. True or False: To solve for $x$, the technician can recall that the equation $\ln e^{4x} = 4$ is equivalent to the exponential equation $e^4 = e^{4x}$.

An industrial electrician is solving the equation $\log_3(4x + 3) = 3$ to determine a circuit's resistance value $x$. Based on the mathematical procedure for this logarithmic equation, the resulting value of $x$ is ____.
