Question

The solution of the pair of linear equations x- y =4 and 3x +2y = 2 is​

Answer 1

Answer:

x = 2 and y = - 2

Step-by-step explanation:

To find solution pair we solve the equations first

Let x - y = 4 - - - (1)

Amd 3x + 2y = 2 - - - (2)

Multiplying (1) by 2

=> 2x - 2y = 8 - - - (3)

On adding (3) and (2)

=> 5x = 10

=> x = 2

Putting x = 2 in (1)

=> 2 - y = 4

=> y = - 2

So solution set is {2, - 2}
