Q17 of 52 Page 3

Find at least 3 solutions for the following linear equation in two variables: 5x + 3y = 4

5x+3y = 4
Take x = 1,
5൱+3y = 4     ⇒ 3y = 4-5 = -1       ∴ y =
Take x = 2,
5൲+3y = 4     ⇒ 3y = 4-10 = -6       ∴ y = = -2
  Take x = 3,
5൳+3y = 4       Þ 3y = 4-15 =-11        ⇒ y = ∴ The three solutions of the given equation are x = 1, y = ; x = 2, y = -2 and x = 3, y =.
