Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Add '-1f2' to each side of the equation.
36 + -1f2 = -3 + f2 + -1f2

Combine like terms: f2 + -1f2 = 0
36 + -1f2 = -3 + 0
36 + -1f2 = -3

Add '-36' to each side of the equation.
36 + -36 + -1f2 = -3 + -36

Combine like terms: 36 + -36 = 0
0 + -1f2 = -3 + -36
-1f2 = -3 + -36

Combine like terms: -3 + -36 = -39
-1f2 = -39

Divide each side by '-1'.
f2 = 39

Simplifying
f2 = 39

Take the square root of each side:
