Hi! Your answer is q = -9
Please see an explanation for a better and clear understanding to your problem.
Any questions about my answer and explanation can be asked through comments! :)
Step-by-step explanation:
Since we want to solve for q-term. That means we are going to isolate q-term.
We can add 4 and 9 together.
Because we want to know the value of q. That means we have to isolate q-term by subtracting both sides by 13.
We are reaching to the final step where we divide the whole equation by 3.
Finally, the solution for this equation is q = -9. But what if you are not certain or sure about the answer? Let's check it out!
To check the answer, simply substitute q = -9 in the equation.
Notice that the equation is true for q = -9. Hence, we can conclude that the solution for this equation is q = -9.
Hope this helps!
Answer:
Step-by-step explanation:
Given the equation
This equation consists of two parts. In the left part, there is a logarithmic function
In the right part, there is a linear function
To solve the equation graphically, you have to plot the graphs of these two functions and find the point of intersection of these graphs.
Hence, appropriate system is
