Introduction

In mathematics, solving for a variable involves isolating the variable on one side of the equation. In this article, we will focus on solving for the variable t in the given equation. We will use a step-by-step approach to simplify the equation and find the value of t.

The Given Equation

The given equation is:

t = 8f - v

We are also given the values of f and v:

f = 9 v = 21

Step 1: Substitute the Given Values

To solve for t, we need to substitute the given values of f and v into the equation.

t = 8(9) - 21

Step 2: Simplify the Equation

Now, we need to simplify the equation by multiplying 8 and 9, and then subtracting 21.

t = 72 - 21

Step 3: Solve for t

Finally, we can solve for t by subtracting 21 from 72.

t = 51

Conclusion

In this article, we solved for the variable t in the given equation. We used a step-by-step approach to simplify the equation and find the value of t. By substituting the given values of f and v, we were able to isolate the variable t and find its value.
