Answer 1

Answer:

x = 28

y=(-4)

here is your answer

Answer 2

Answer:

x = 12 ; y = 4

Explanation:

i) x - 3y =0 ; ii) x +2y = 20

If :

x = 3 y

So :

= x + 2y = 20

= (3y) + 2y = 20

= 3y + 2y = 20

= 5y = 20

= y = 20/ 5

= y = 4

Then :

= x = 3y

= x = 3(4)

= x = 12

Hence :

x = 12 ; y = 4
