Question

To convert the pair of equations to pair of linear equations, the appropriate substitution is
1 point
p = 1/x, and q = 1/y
p = 1/(x-y), and q = 1/(x+y)
p = 1/(y-x), and q = 1/(x+y)
p = (x-y), and q = (x+y)

Answer 1

Answer:

Lets assume

x

1

=p and

y

1

=q, both equations will become

2

p

+

3

q

=2

⇒3p+2q=12 ... (A)

3

p

+

2

q

=

6

13

⇒2p+3q=13 ...(B)

Multiply (A) by 3 and (B) by 2, we get

9p+6q=36

4p+6q=26

Subtracting these both, we get

5p=10

⇒p=2

⇒x=

p

1

=

2

1

∴q=

6

26−8

=3

⇒y=

q

=
