Question

2x+y=13;2x-3y=9 simaltaneous eqn​

Answer 1

Question :-

2x+y=13;2x-3y=9 simultaneous eqⁿ.

Answer :-

• x = 6
• y = 1

Step by step explanation :-

Given that,

2x + y = 13 ————(1)

2x - 3y = 9 ————(2)

Now, Subtract eqⁿ (2) from eqⁿ (1)

⇒ 2x + y - (2x - 3y) = 13 - 9

⇒ 2x - 2x + y + 3y = 4

⇒ 4y = 4

⇒ y = 4/4

⇒ y = 1

Substitute y = 1 in eqⁿ (1)

⇒ 2x + 1 = 13

⇒ 2x = 13 - 1

⇒ 2x = 12

⇒ x = 12/2

⇒ x = 6
