Question

{3x=7y=5
{5x-2y=-19

Answer 1

(-3, 2)

Explanation:

{3x=7y=5

{5x-2y=-19

solve....

maybe it was 3x + 7y = 5

and 5x - 2y = -19

2*(3x + 7y = 5)

7*(5x - 2y = -19)

-------------

6x + 14y = 10

35x -14y = -133

41x = -123

x = -3

y = ...

5*(-3) - 2y = -19

-15 - 2y = -19

2y = 4

y = 2

(-3, 2)
