Clue 5
Two-step equations — the last clue
To solve the secret path code, the team set up a balanced scale equation.
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
4x + 1 = 25, x = ?
5x + 6 = 51, x = ?
2x + 4 = 6, x = ?
6x + 4 = 52, x = ?
4x + 1 = 45, x = ?
6x + 12 = 54, x = ?
5x + 3 = 53, x = ?
6x + 6 = 78, x = ?
5x + 5 = 25, x = ?
4x + 1 = 13, x = ?
3x + 9 = 24, x = ?
Step 2 — cross out the sentence with each answer
1.The villain climbed the giant canopy tree, then pitched a green camo tent.
2.The villain chattered with the wild parrots, then checked a brass compass.
3.The villain paddled down the swift river, then lit a bright campfire torch.
4.The villain chattered with the wild parrots, then pitched a green camo tent.
5.The villain read the ancient stone map, then dodged a hidden rope trap.
6.The villain swung on a long jungle vine, then lit a bright campfire torch.
7.The villain paddled down the swift river, then dodged a hidden rope trap.
8.The villain climbed the giant canopy tree, then dodged a hidden rope trap.
9.The villain chattered with the wild parrots, then tied a tight sailor knot.
10.The villain climbed the giant canopy tree, then lit a bright campfire torch.
11.The villain climbed the giant canopy tree, then checked a brass compass.
12.The villain climbed the giant canopy tree, then tied a tight sailor knot.
