Respuesta :

Answer:

Question 1

No solution

Question 3

No solution

Explanation:

Given the pair of equations:

5x + 2y = -7

15x + 6y = 21

Notice that the second equation can be obtained by mulitiplying the first equation by 3, this makes the pair have no solution.

A pair of equations where one is a multiple of the other has no soution.

Similarly for

6x + 4y = 10

3x + 2y = 5

No solution
