Q1:

Solve the simultaneous equations π‘₯ βˆ’ 𝑦 = 8 and 3 π‘₯ βˆ’ 5 𝑦 + 1 0 = 0 .

  • A π‘₯ = 2 5 , 𝑦 = 1 7
  • B π‘₯ = βˆ’ 9 , 𝑦 = 1 7
  • C π‘₯ = 2 5 , 𝑦 = βˆ’ 1 7
  • D π‘₯ = 1 7 , 𝑦 = 2 5

Q2:

Use the elimination method to solve the simultaneous equations

  • A π‘₯ = 2 and 𝑦 = 2
  • B π‘₯ = 1 and 𝑦 = βˆ’ 1
  • C π‘₯ = βˆ’ 1 6 and 𝑦 = βˆ’ 1 4
  • D π‘₯ = 1 and 𝑦 = 1
  • E π‘₯ = βˆ’ 1 4 and 𝑦 = βˆ’ 1 6

Q3:

Using elimination, solve the simultaneous equations

  • A π‘₯ = 9 , 𝑦 = 1
  • B π‘₯ = 1 9 , 𝑦 = 1 1
  • C π‘₯ = 9 , 𝑦 = βˆ’ 1
  • D π‘₯ = 1 7 , 𝑦 = 1
  • E π‘₯ = 1 7 , 𝑦 = 4
