Clue 1

Integers

To decode the suspect's elevation trail, you must calculate the net change from a series of drops and climbs in the deep subterranean shafts.

Clue 5

Two-step equations — the last clue

You find a heavy scale balanced with basalt blocks. Solve the two-step algebraic riddle of the weights to unlock the final room.

First solve each problem. Then find each answer in the list below and cross that sentence out. One sentence will be left — that's exactly what the villain did!

Step 1 — solve these
6x + 4 = 70, x = ?
6x + 4 = 76, x = ?
4x + 11 = 43, x = ?
6x + 12 = 72, x = ?
3x + 10 = 31, x = ?
2x + 11 = 29, x = ?
3x + 6 = 18, x = ?
2x + 11 = 15, x = ?
3x + 9 = 12, x = ?
5x + 5 = 20, x = ?
2x + 7 = 19, x = ?
Step 2 — cross out the sentence with each answer
1.The villain lights up the dark tunnel with a heavy headlamp, then snatches the shining crystal prism.
2.The villain scouts the ruins with brass binoculars, then swipes the obsidian scarab relic.
3.The villain uses a climbing harness to scale the temple wall, then grabs the noisy bronze whistle.
4.The villain clears path brush with a sharp machete, then pockets the priceless gold medallion.
5.The villain clears path brush with a sharp machete, then swipes the obsidian scarab relic.
6.The villain scouts the ruins with brass binoculars, then pockets the priceless gold medallion.
7.The villain clears path brush with a sharp machete, then grabs the noisy bronze whistle.
8.The villain uses a climbing harness to scale the temple wall, then steals the ancient jade compass.
9.The villain uses a climbing harness to scale the temple wall, then swipes the obsidian scarab relic.
10.The villain scouts the ruins with brass binoculars, then grabs the noisy bronze whistle.
11.The villain clears path brush with a sharp machete, then snatches the shining crystal prism.
12.The villain lights up the dark tunnel with a heavy headlamp, then pockets the priceless gold medallion.
