s u b s t i t u t e y = 2 y 3 + 5 y → 2 3 + 5 ⋅ 2 = 8 + 10 = 18 ← so l u t i o n
2 3 + 5 ⋅ 2 = 8 + 10 = 18
When you substitute y = 2 into the expression y 3 + 5 y , you first compute 2 3 = 8 and 5 ⋅ 2 = 10 . Adding these results together gives you 18 as the final answer. Therefore, y 3 + 5 y = 18 when y = 2 .
