Final answer:
The equation provided is a basic algebra problem where the student needs to solve for the variable k. By multiplying both sides by 3 and then dividing by 7, we find that k equals 9.
Step-by-step explanation:
The student has presented the equation 7k divided by 3 = 21 and is likely seeking assistance with solving for the variable k. To solve this equation, one would typically isolate the variable by performing inverse operations. Here are the steps you would follow:
- Multiply both sides of the equation by 3 to get rid of the denominator on the left side, which gives us 7k = 63.
- Next, divide both sides of the equation by 7 to solve for k, which results in k = 9.
Therefore, the solution to the equation is k = 9.
