Solving for f in the Equation 6f + 9g = 3g + f

Understanding the Equation

The given equation is 6f + 9g = 3g + f. To solve for f, we need to isolate the variable f on one side of the equation. This involves simplifying the equation and using algebraic techniques to isolate f.

Step 1: Simplify the Equation

The first step is to simplify the equation by combining like terms. We can start by subtracting 3g from both sides of the equation:

6f + 9g - 3g = 3g - 3g + f

This simplifies to:

6f + 6g = f

Step 2: Isolate f

Next, we need to isolate f on one side of the equation. We can do this by subtracting f from both sides of the equation:

6f - f + 6g = f - f

This simplifies to:

5f + 6g = 0

Step 3: Solve for f

Now, we need to solve for f. We can do this by subtracting 6g from both sides of the equation:

5f = -6g

Next, we can divide both sides of the equation by 5:

f = -6g/5

Conclusion

Therefore, the solution to the equation 6f + 9g = 3g + f is f = -6g/5.

Comparing the Solution to the Options

Let's compare the solution to the options:

A. f = -8g/3 B. f = -6g/5 C. f = -5g/6 D. f = 12g/7

The only option that matches the solution is option B: f = -6g/5.
