Use the grid to match each contestant to their problem-solving round, their chosen strategy, and the equation type they focused on. Each option is used exactly once per column.
Clues:
• Diego’s Equation Type was Simultaneous equations.
• The Draw a diagram used the Quadratic equation.
• It isn’t true that Carter didn’t use the Inequality with the Eliminate options.
• The person at the 11:00 used the Simultaneous equations.
• The Work backwards was scheduled at the 9:00.
• Andrew’s Round Time was 10:00.
• The Work backwards used the Linear equation.
• Make a table was scheduled later than Draw a diagram.
| Name | Round Time | Strategy | Equation Type |

Equation Detective – Medium
Work in layers: direct → elimination → relationship → backfill.
Layer 1: place all definite positives.
Layer 2: apply elimination rules (one-in-each row/column).
Layer 3: translate the “maths” clues:
more/less = difference, twice/half = multiplication, total = addition.
Layer 4: when a category is nearly complete, backfill the last remaining option automatically.
Pro tip: don’t “solve prices” separately — place them in the grid as soon as they’re known so they can trigger more eliminations.
