Solve the equation
2 1 6
—— + —— = ——
8 n 12
Reduce the fractions at the left side to the same denominator:
2n 8 6
—— + —— = ——
8n 8n 12
2n + 8 6
———— = ——
8n 12
(2n + 8) · 12 = 8n · 6
2n · 12 + 8 · 12 = 8n · 6
24n + 96 = 48n
24n – 48n = – 96
– 24n = – 96
– 96
n = ———
– 24
n = 4 <———— this is the solution.
I hope this helps. =)
