Answer 2

Answer:

x=5,y=6

Step-by-step explanation:

given,  6x+2y=42................(1)

           -6x+12y=42..............(2)

adding (1) and (2)

                  6x+2y-6x+12y=42+42

                   14y=84

                     y=$\frac{84}{14}$

                       y=6,

y=6 put in equation (1)

6x+2times{6}=42

6x=42-12=30

x=$\frac{30}{6}$

x=5
