Answer:

x = 2

y = 10

Step-by-step explanation:

6y = 12x + 36

6y -12x = 36

15y = 45x + 60

15y - 45x = 60

6y -12x = 36 | ×15 |

15y - 45x = 60 | ×6 |

90y -180x = 540

90y - 270x = 360

_______________--

90x = 180

x = 180/90

x = 2

6y -12x = 36

6y - 12(2) = 36

6y - 24 = 36

6y = 36 + 24

6y = 60

y = 60/6

y = 10
