Q18 of 52 Page 3

Find at least 3 solutions for the following linear equation in two variables: 2x + 3y = 4

2x+3y = 4
Take x = 1,
2 ൱+3y = 4
    ⇒  3y = 4 - 2 = 2
      ∴  y =
  Take x = 2,
2 × 2 + 3y = 4
  ⇒ 3y = 4 - 4 = 0
      ∴ y = 0
  Take x = 3,
2 × 3+3y = 4
     ⇒  3y = 4 - 6 = -2
     ⇒  y =
∴ The three solutions of the given equation are x = 1, y = ; x = 2, y = 0 and x = 3, y =.
