(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 = 3F
-1 + 3F = 2(3 + F)
-1 + 3F = (3 * 2 + F * 2)
-1 + 3F = (6 + 2F)

Solving
-1 + 3F = 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 + 3F + -2F = 6 + 2F + -2F

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

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

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

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

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

Divide each side by '1'.
F = 7

Simplifying
F = 7
