13x−6y=22 x=y+6 ​ whats the answer

Mathematics
1 answer:
Vikentia [17]2 years ago
4 0

Answer:

x = -2 y = -8

Step-by-step explanation:

13x - 6y = 22

x - y = 6

6(x-y) = 6*6

6x - 6y = 36

subtract both the equations

13x - 6x -6y + 6y = -14

7x = -14

x = -2

13*-2 -6y=22

-26 -6y=22

-6y = 48

y = -8

answer: x = -2  y = -8
