w=2(n+20)+.3(n+20)

Solution for w=2(n+20)+.3(n+20) equation:

Simplifying
w = 2(n + 20) + 0.3(n + 20)

Reorder the terms:
w = 2(20 + n) + 0.3(n + 20)
w = (20 * 2 + n * 2) + 0.3(n + 20)
w = (40 + 2n) + 0.3(n + 20)

Reorder the terms:
w = 40 + 2n + 0.3(20 + n)
w = 40 + 2n + (20 * 0.3 + n * 0.3)
w = 40 + 2n + (6 + 0.3n)

Reorder the terms:
w = 40 + 6 + 2n + 0.3n

Combine like terms: 40 + 6 = 46
w = 46 + 2n + 0.3n

Combine like terms: 2n + 0.3n = 2.3n
w = 46 + 2.3n

Solving
w = 46 + 2.3n

Solving for variable 'w'.
