Clue 1

Integers

The stadium scoreboard recorded temperature shifts and gain-loss yardage in the storage hangar. You balance the negative and positive integer logs to decode the first lead.

Clue 5

Two-step equations — the last clue

The stadium fueling terminal balances truck fuel capacities against weight distribution equations. Solving the two-step equation gives you the final suspect coordinates.

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
3x + 6 = 18, x = ?
6x + 1 = 61, x = ?
3x + 1 = 4, x = ?
5x + 7 = 32, x = ?
2x + 3 = 7, x = ?
4x + 9 = 57, x = ?
4x + 9 = 53, x = ?
4x + 11 = 43, x = ?
2x + 9 = 23, x = ?
2x + 12 = 24, x = ?
5x + 11 = 26, x = ?
Step 2 — cross out the sentence with each answer
1.The villain snaps a curveball, then speeds away in a semi truck.
2.The villain smashes a slam dunk, then boards a freight plane.
3.The villain smashes a slam dunk, then speeds away in a semi truck.
4.The villain smashes a slam dunk, then escapes in a cargo jet.
5.The villain smashes a slam dunk, then drives off in a big rig.
6.The villain smashes a slam dunk, then vanishes in a delivery van.
7.The villain sinks a sky hook, then speeds away in a semi truck.
8.The villain launches a long drive, then vanishes in a delivery van.
9.The villain launches a long drive, then speeds away in a semi truck.
10.The villain sinks a sky hook, then vanishes in a delivery van.
11.The villain sinks a sky hook, then drives off in a big rig.
12.The villain hurls a fastball, then boards a freight plane.
