ahhhhh! I'm tiiiiired

Answer 1

Step-by-step explanation:

Given

- 4x + 11y = 15.......equation 1

x = 2y.......equation 2

Now putt x = 2y in equation 1

- 4 * 2y + 11y = 15

- 8y + 11y = 15

3y = 15

Therefore y = 5

Now

x = 2* 5

= 10

Hope it will help you.

Answer 2

if you solve it you get X=10
