Answer 1

Answer:

= 10 Y -3

= 7Y

= 7Y+2Y

= 9Y

=9Y+1

= 10Y +17Y

Answer 2

Step-by-step explanation:

As per the given data,

⇒ x + 2y = 27 ---- equation (1)

⇒ x – 2y = -1 ---- equation (2)

By adding equation (1) and equation (2), we get

⇒ 2x = 26

⇒ x = 26/2 = 13

Substitute x = 13 in equation (1), we get

⇒ 13 + 2y = 27

⇒ 2y = 27 – 13

⇒ 2y = 14

⇒ y = 14/2 = 7

∴ y = 7
