Question 1 · 1 mark · Difficulty 1/3

Which of the following best describes a system of simultaneous linear equations in two variables?

  1. A single equation with two unknowns that has infinitely many solutions
  2. Two or more equations that are solved together to find values satisfying all equations
  3. Two equations where each is solved separately for one variable
  4. A quadratic equation written in two different forms
Show answer & explanation
✓ Answer: BTwo or more equations that are solved together to find values satisfying all equations
Simultaneous equations are two or more equations considered together, and the solution must satisfy all equations at the same time. Solving them separately or treating them as a single equation are common misconceptions.
Question 2 · 1 mark · Difficulty 1/3

Solve the simultaneous equations: x + y = 7 and x − y = 3. What is the value of x?

  1. x = 2
  2. x = 5
  3. x = 4
  4. x = 3
Show answer & explanation
✓ Answer: Bx = 5
Adding the two equations gives 2x = 10, so x = 5. Substituting back gives y = 2. A common error is subtracting instead of adding, which would give only the value of y.
