A student showed the steps below while solving the equation by graphing. Step 1: Write a system of equations: Step 2: Use the ch
ange 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
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.
