Question

ing equations using substitution
(ii) x-y = 2
x+y = 18​

Answer 1

Answer:

x = 8

y = 10

Step-by-step explanation:

GIVEN EQUATIONS:-

x - y = 2 (eq. 1)

x + y = 18(eq. 2)

SO,

IN EQUATION 1,

x - y = 2

x = 2+y

NOW,

SUBSTITUTING THE VALUE OF x IN EQUATION 2,

WE GET,

⇒x + y = 18

⇒ (2+y) + y = 18

⇒ 2+2y = 18

⇒ 2y = 16

⇒ y = 8

SO,

x = 2+y

  = 2+8

  = 10

SO,

⇒x = 8

⇒y = 10
