Q21 of 52 Page 3

Find at least 3 solutions for the following linear equation in two variables: 2x-3y= -11

2x-3y = -11
Take x = 1,
2x-3y = -11   ⇒ -3y = -11-2 = -13      ∴ y = =
  Take x = 2,
2x -3y = -11     ∴ -3y = -11-4
       -3y = -15         ∴ y = 5
Take x = 3,
2x-3y = -11    ⇒ -3y = -11-6 = -17       ∴ y = ∴ The three solutions of the given equation are x = 1, y = ; x = 2, y = 5 and x = 3, y =.
