(F-1)-2F=2(3+F)

Solution for (F-1)-2F=2(3+F) equation:

Simplifying
(F + -1) + -2F = 2(3 + F)

Reorder the terms:
(-1 + F) + -2F = 2(3 + F)

Remove parenthesis around (-1 + F)
-1 + F + -2F = 2(3 + F)

Combine like terms: F + -2F = -1F
-1 + -1F = 2(3 + F)
-1 + -1F = (3 * 2 + F * 2)
-1 + -1F = (6 + 2F)

Solving
-1 + -1F = 6 + 2F

Solving for variable 'F'.

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

Add '-2F' to each side of the equation.
-1 + -1F + -2F = 6 + 2F + -2F

Combine like terms: -1F + -2F = -3F
-1 + -3F = 6 + 2F + -2F

Combine like terms: 2F + -2F = 0
-1 + -3F = 6 + 0
-1 + -3F = 6

Add '1' to each side of the equation.
-1 + 1 + -3F = 6 + 1

Combine like terms: -1 + 1 = 0
0 + -3F = 6 + 1
-3F = 6 + 1

Combine like terms: 6 + 1 = 7
-3F = 7

Divide each side by '-3'.
F = -2.333333333

Simplifying
F = -2.333333333
