Answer» 7x - 4y - 49 = 0 ......(1) 5x - 6y - 57 = 0 .......(2) So, here we have 7/5 is not equal to -4/-6 = 2/3 Therefore unique solution exists. To solve 3 × eq(1) - 2 × eq (2) 21x - 12y - 147 = 010x - 12y - 114 = 0 Solving we get11x - 147 + 114 = 011x - 33 = 011x = 33x = 3 So, from (1)21 - 4y - 49 = 0- 4y - 28 = 04y = -28y = -28/4 = -7

Answer»

7x - 4y - 49 = 0 ......(1)

5x - 6y - 57 = 0 .......(2)

So, here we have

7/5 is not equal to -4/-6 = 2/3

Therefore unique solution exists.

To solve 3 × eq(1) - 2 × eq (2)

21x - 12y - 147 = 010x - 12y - 114 = 0

Solving we get11x - 147 + 114 = 011x - 33 = 011x = 33x = 3

So, from (1)21 - 4y - 49 = 0- 4y - 28 = 04y = -28y = -28/4 = -7
