Question

A student showed the steps below while solving the equation by graphing. Step 1: Write a system of equations: Step 2: Use the change of base formula to rewrite the equations: Step 3: Graph the two equations: Step 4: Identify the x-value at the point of intersection: In which step did the student make the first mistake? step 1 step 2 step 3 step 4

Answer 1

Answer:

Step 2

Step-by-step explanation:

Process of elimination can help us here.

Step one, write a system of equations. This is a given, so this can't be wrong.

Step three, graph the equations. At first, this may seem wrong, but it works because of step four, Identify the x-value at the point of intersection. Neither of these can be wrong.

That leaves us with step two.

Answer 2

Answer:

The answer is  below while solving the equation by graphing.

Step 4: Identify the x-value at the point of intersection:

x=4.5
