Solution for f-6=-(f+8) equation:

Simplifying
f + -6 = -1(f + 8)

Reorder the terms:
-6 + f = -1(f + 8)

Reorder the terms:
-6 + f = -1(8 + f)
-6 + f = (8 * -1 + f * -1)
-6 + f = (-8 + -1f)

Solving
-6 + f = -8 + -1f

Solving for variable 'f'.

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

Add 'f' to each side of the equation.
-6 + f + f = -8 + -1f + f

Combine like terms: f + f = 2f
-6 + 2f = -8 + -1f + f

Combine like terms: -1f + f = 0
-6 + 2f = -8 + 0
-6 + 2f = -8

Add '6' to each side of the equation.
-6 + 6 + 2f = -8 + 6

Combine like terms: -6 + 6 = 0
0 + 2f = -8 + 6
2f = -8 + 6

Combine like terms: -8 + 6 = -2
2f = -2

Divide each side by '2'.
f = -1

Simplifying
f = -1
