Solving for variable 'f'.

Factor out the Greatest Common Factor (GCF), 'fs'.
fs(7 + 2s + 10f) = 0

Subproblem 1

Set the factor 'fs' equal to zero and attempt to solve: Simplifying fs = 0 Solving fs = 0 Move all terms containing f to the left, all other terms to the right. Simplifying fs = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(7 + 2s + 10f)' equal to zero and attempt to solve: Simplifying 7 + 2s + 10f = 0 Reorder the terms: 7 + 10f + 2s = 0 Solving 7 + 10f + 2s = 0 Move all terms containing f to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + 10f + -7 + 2s = 0 + -7 Reorder the terms: 7 + -7 + 10f + 2s = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 10f + 2s = 0 + -7 10f + 2s = 0 + -7 Combine like terms: 0 + -7 = -7 10f + 2s = -7 Add '-2s' to each side of the equation. 10f + 2s + -2s = -7 + -2s Combine like terms: 2s + -2s = 0 10f + 0 = -7 + -2s 10f = -7 + -2s Divide each side by '10'. f = -0.7 + -0.2s Simplifying f = -0.7 + -0.2s

Solution

f = {-0.7 + -0.2s}
