x=5411

y=1311

Explanation:

x+6y=12 and 3x+4y=10

or

x=6y12

or

x=6(y2)

Multiplying x+6y=12 by 3

We get

3x+18y=36

By adding 3x+18y=36 with 3x+4y=10

We get

3x+18y+3x+4y=3610

or

22y=26

or

y=2622

or

y=1311----------------------Ans 1

By plugging the value y=1311 in the equation x=6(y2)

We get

x=6(13112)

or

x=6×132211

or

x=6×(911)

or

x=5411---------------------Ans 2
