u=2(9n+32)+3(n+1)

Solution for u=2(9n+32)+3(n+1) equation:

Simplifying
u = 2(9n + 32) + 3(n + 1)

Reorder the terms:
u = 2(32 + 9n) + 3(n + 1)
u = (32 * 2 + 9n * 2) + 3(n + 1)
u = (64 + 18n) + 3(n + 1)

Reorder the terms:
u = 64 + 18n + 3(1 + n)
u = 64 + 18n + (1 * 3 + n * 3)
u = 64 + 18n + (3 + 3n)
