Question

write two solutions for each of the following 1) 2x + y = 7 2) pi x + y = 9 3) x = 4y​

Answer 1

Answer:

Two solutions for each of the following are

1. (0,7) and (1,5)

2. (0,9) and (1 ,9 – π)

3. (0,0) and (1, 1/4)

Explanation:

1. Put x = 0

2 × 0 + y = 7 => y = 7

solution = (0,7)

_______________

Put x = 1

2 × 1 + y = 7

=> 2 + y = 7 => y = 7 – 2 = 5

solution = (1,5)

________________________________________________

2. Put x = 0

π × 0 + y = 9

=> y = 9

solution = (0,9)

____________

Put x = 1

=> π × 1 + y = 9

=> y = 9 – π

solution = (1, 9 – π)

________________________________________________

3. x/4 = y

Put x = 0

0/4 = y => y = 0

solution = (0,0)

___________________

Put x = 1

1/4 = y

solution = (1, 1/4)
