Question

substitution method 2x-y=5,3x+2y=11​

Answer 1

Answer:

The given two equations are

2x – y = 5 …..(I)

3x + 2y = 11 ….(II)

Multiplying (I) with 2 we get

4x – 2y = 10 ….(III)

Adding (II) with (III)

7x = 21

x = 3

Putting the value of x in (I) we get

2 × 3 − y = 5

⇒ 6 − y = 5

⇒ y=1

Answer 2

Answer:

= y=1

Step-by-step explanation:

Solve 2x - y = 5 and 3x + 2y = 11 by substitution.

The given two equations are

2x – y = 5 …..(I)

3x + 2y = 11 ….(II)

Multiplying (I) with 2 we get

4x – 2y = 10 ….(III)

Adding (II) with (III)

7x = 21

x = 3

Putting the value of x in (I) we get

2 × 3 − y = 5

⇒ 6 − y = 5

⇒ y=1
