Question

the pair of equations 3x+2y=13 and 3x-2y=5 has​

Answer 1

Answer:

Step-by-step explanation:

3x + 2y = 13  ,  3x - 2y = 5

by adding

6x = 18                 x = 3

3(3) + 2y = 13      y = 2

x+y = 3+2 = 5

Answer 2

Answer:

The given pair of equations have a unique solution.

Step-by-step explanation:

Here, a1/a2 is not equal to b1/b2

Hence, unique solution.

Solution is x = 3; y =2
