Q11Multiple choiceExercise 3.3
By the graphical method, find whether the following pair of equations are consistent or not. If consistent, solve them.
- (i)3x + y + 4 = 0
- (ii)x – 2y = 6 6x – 2y + 4 = 0 3x – 6y = 0
- (iii)x + y = 3 3x + 3y = 9
Show answer
(i) 3x + y + 4 = 0
(ii) x – 2y = 6 6x – 2y + 4 = 0 3x – 6y = 0
(iii) x + y = 3 3x + 3y = 9
