Answer:

x = 2

y = 3

Step-by-step explanation:

6x + 6y = 30 ...(1)

15x - 6y = 12 ...(2)

Using Elimination method,

Add (1) to (2)

21x = 42

Divide both sides by 21

x = 42/21 = 2

x = 2

Substitute x = 2 in (1)

6(2) + 6y = 30

12 + 6y = 30

6y = 30 - 12 = 18

6y = 18

Divide both sides by 6

y = 3
