u=2(8n+34)+2(n+1)

Solution for u=2(8n+34)+2(n+1) equation:

Simplifying
u = 2(8n + 34) + 2(n + 1)

Reorder the terms:
u = 2(34 + 8n) + 2(n + 1)
u = (34 * 2 + 8n * 2) + 2(n + 1)
u = (68 + 16n) + 2(n + 1)

Reorder the terms:
u = 68 + 16n + 2(1 + n)
u = 68 + 16n + (1 * 2 + n * 2)
u = 68 + 16n + (2 + 2n)
