Question

Find the relation between p and q if x = 3 and y = 1 is the solution of the pair of equations x – 4y + p = 0 and 2x + y – q – 2 = 0.

Answer 1

Answer:

x-4y+p=0 ...... (1)

2x+y-q-2=0 ...... (2)

(1) +(2)

x-4y+p+2x+y-q-2=0

3x-3y+p-q=0

3(3) -3(1) +p-q=0

9-3+p-q=0

6+p-q=0

p-q=-6

hope it is helpful.

pls mark me as brainliest....

Answer 2

Answer:

x-4y+p=0 ...... (1)

2x+y-q-2=0 ...... (2)

(1) +(2)

x-4y+p+2x+y-q-2=0

3x-3y+p-q=0

3(3) -3(1) +p-q=0

9-3+p-q=0

6+p-q=0

p-q=-6
