Answer 1

Answer:

By elimination method

12x-5y=22---1

12x+5y=2---2

changing the sign of 2 equation

12x will get eliminated

-10y=20

y=-2

x=1

Answer 2

Answer:

Step-by-step explanation:

12x-5y = 22 -----------------------------1

12x + 5y = 2--------------------------------2

1+2

12x - 5y = 22

12x + 5y = 2

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

24x=24

x= 1

substitue x value in 2

12+5y = 2

5y = -10

y = -2
