Question 1 — Easy
Solve the simultaneous equations: 2x + y = 10 and x − y = 2.
Answer: Option A is correct — Add the two equations to eliminate y: (2x + y) + (x − y) = 10 + 2 → 3x = 12 → x = 4. Substitute into x − y = 2: 4 − y = 2 → y = 2.
Question 2 — Medium
Priya is training for a school swimming carnival. She swims a total of 15 laps, which is 3 more than twice the number of laps she swam yesterday. Which equation represents this situation, and what is the solution?
Answer: The equation is 2x + 3 = 15. Subtracting 3 from both sides gives 2x = 12, then dividing by 2 gives x = 6. Substituting back: 2(6) + 3 = 15 ✓. Option A results from dividing 15 by 3 instead of solving the equation. Option C adds 3 instead of subtracting it. Option D halves 15 without accounting for the +3.
Question 3 — Hard
Zac and Mei are collecting cans for a school fundraiser. Together they have collected 45 cans. Zac collected 3 more than twice the number Mei collected. How many cans did Mei collect?
Answer: Let m = the number of cans Mei collected. Then Zac collected 2m + 3. The equation is m + (2m + 3) = 45, which simplifies to 3m + 3 = 45, giving 3m = 42, so m = 14. Substituting back: Mei = 14, Zac = 31, total = 45 ✓. Option B (16) gives Zac = 35, total = 51 ≠ 45. Option C (21) gives Zac = 45, total = 66 ≠ 45. Option D (24) gives Zac = 51, total = 75 ≠ 45.
