For this case we must solve the following equation:
For this, we follow the steps below:
We find the Neperian logarithm on both sides of the equation to remove the variable from the exponent
We use one of the logarithm properties to extract x from the exponent:
We subtract xln (7) on both sides of the equation:
We take x common factor:
We divide betweenon both sides of the equation, then:
Answer:
