The scale is balanced. The left pan holds weights of 3p kg and 5 kg; the right pan holds (p + 2) kg and an unknown weight. Using the tag, what is the unknown weight?

Question

Accepted Answer

11 kg. With p = 4: left pan = 3 × 4 + 5 = 17 kg, and p + 2 = 6 kg. Balanced pans are equal, so ? = 17 - 6 = 11 kg.

The scale is balanced. The left pan holds weights of $3 p$ kg and 5 kg; the right pan holds $(p + 2)$ kg and an unknown weight. Using the tag, what is the unknown weight?
