F(n)=-71(n-1)4.2

Solution for F(n)=-71(n-1)4.2 equation:

Simplifying
F(n) = -71(n + -1) * 4.2

Multiply F * n
nF = -71(n + -1) * 4.2

Reorder the terms:
nF = -71(-1 + n) * 4.2

Reorder the terms for easier multiplication:
nF = -71 * 4.2(-1 + n)

Multiply -71 * 4.2
nF = -298.2(-1 + n)
nF = (-1 * -298.2 + n * -298.2)
nF = (298.2 + -298.2n)

Solving
nF = 298.2 + -298.2n

Solving for variable 'n'.

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

Add '298.2n' to each side of the equation.
298.2n + nF = 298.2 + -298.2n + 298.2n

Combine like terms: -298.2n + 298.2n = 0.0
298.2n + nF = 298.2 + 0.0
298.2n + nF = 298.2

Reorder the terms:
-298.2 + 298.2n + nF = 298.2 + -298.2

Combine like terms: 298.2 + -298.2 = 0.0
-298.2 + 298.2n + nF = 0.0

The solution to this equation could not be determined.
