Question

given below a pair of simultaneus equation,
4x+y=14
2x-3y=0

Answer 1

Answer:

Disclaimer:

There is error in the

Q. In (II) there should have been 2x - 3y = 12

5x + 3y = 9 -----(I)

5x + 3y = 9 -----(I)2x - 3y = 12 ----- (II)

Add (I) and (II)

• 7x = 21
• 7x = 21x = 3
• 7x = 21x = 3Putting the value of x = 3 in (I) we get
• 7x = 21x = 3Putting the value of x = 3 in (I) we get5(3)+3y=9⇒15+3y=9⇒3y=9-15=-6⇒y=-2
• 7x = 21x = 3Putting the value of x = 3 in (I) we get5(3)+3y=9⇒15+3y=9⇒3y=9-15=-6⇒y=-2Thus, (x, y) = (3, -6).

Answer 2

this is the perfect and correct answer of this question.
