Answer 2

x + y = 4

⇒ x = 4 - y

2x - 5y = 1

Substituting for x:

⇒ 2(4 - y) - 5y = 1

⇒ 8 - 2y - 5y = 1

⇒ 8 - 7y = 1

⇒ 8 - 1 = 7y

⇒ 7 y = 7

∴ y = 1

Substituting value of y in any one equation:

x + y = 4

→ x + 1 = 4

→ x = 4 - 1 = 3

∴ x = 3

Answer:

x = 3 and y = 1

Verification:

x + y = 4

⇒ 3 + 1 = 4

LHS = RHS

Hence verified
