About a day late, but ... it already isolated one of the variables for you, so you can just take the first equation and substitute it into the second:

2x - 3 (5x - 6) = 4

2x - 15x + 18 = 4

-13x + 18 = 4

-13x = - 14

x = 14/13

based on that alone, you can see that B is your answer, but you can still plug it in to make sure:

5 (14/13) - 6 = y

(70/13) - 6 = y

y = - 8/13

your answer is B
