u=2(9n+31)+3(n+11)

Solution for u=2(9n+31)+3(n+11) equation:

Simplifying
u = 2(9n + 31) + 3(n + 11)

Reorder the terms:
u = 2(31 + 9n) + 3(n + 11)
u = (31 * 2 + 9n * 2) + 3(n + 11)
u = (62 + 18n) + 3(n + 11)

Reorder the terms:
u = 62 + 18n + 3(11 + n)
u = 62 + 18n + (11 * 3 + n * 3)
u = 62 + 18n + (33 + 3n)

Reorder the terms:
u = 62 + 33 + 18n + 3n

Combine like terms: 62 + 33 = 95
u = 95 + 18n + 3n
