-6=2.5(w-2n)

Solution for -6=2.5(w-2n) equation:

Simplifying
-6 = 2.5(w + -2n)

Reorder the terms:
-6 = 2.5(-2n + w)
-6 = (-2n * 2.5 + w * 2.5)
-6 = (-5n + 2.5w)

Solving
-6 = -5n + 2.5w

Solving for variable 'n'.

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

Add '5n' to each side of the equation.
-6 + 5n = -5n + 5n + 2.5w

Combine like terms: -5n + 5n = 0
-6 + 5n = 0 + 2.5w
-6 + 5n = 2.5w

Add '6' to each side of the equation.
-6 + 6 + 5n = 6 + 2.5w

Combine like terms: -6 + 6 = 0
0 + 5n = 6 + 2.5w
5n = 6 + 2.5w

Divide each side by '5'.
n = 1.2 + 0.5w

Simplifying
n = 1.2 + 0.5w
