Question

Example 12: Use elimination method to find all possible solutions of the following
pair of linear equations:
2x + 3y = 8
4x + 6y = 7
​

Answer 1

Answer:

the pair of linear equations doesn't have any solution

Answer 2

Answer:

⇒2x+3y=8

⇒4x+6y=7

2x+3y=8*4

4x+6y=7*2

8x+12y=32

8x+12y=14

(if the sign is not opposite then we have to make it opposite)

8x+12y=32

8x+12y=14
