$- 1 + 2 f = - 8 + 6 f - 3 f$

Step 1

Since $f$ is on the right side of the equation, switch the sides so it is on the left side of the equation.

$- 8 + 6 f - 3 f = - 1 + 2 f$

Step 2

Subtract $3 f$ from $6 f$ .

$- 8 + 3 f = - 1 + 2 f$

Step 3

Move all terms containing $f$ to the left side of the equation.

Step 3.1

Subtract $2 f$ from both sides of the equation.

$- 8 + 3 f - 2 f = - 1$

Step 3.2

Subtract $2 f$ from $3 f$ .

$- 8 + f = - 1$

Step 4

Move all terms not containing $f$ to the right side of the equation.

Step 4.1

Add $8$ to both sides of the equation.

$f = - 1 + 8$

Step 4.2

Add $- 1$ and $8$ .

$f = 7$
