Question

3. Write 3 solutions of the given equation x + y = 4.
(3 marks)​

Answer 1

Answer:

3 solutions are

x=4

y=0

x=0

y=4

x=3

y=1

Answer 2

Answer:

x+y=4

Put x=2

We get,

2+y=4

y=4-2

y=2(1st solution)

x+y=4

Put x=1

1+y=4

y= 4-1

y= 3 (2nd solution)

x+y=4

Put x=0

0+y=4

y= 4-0

y= 4 (3rd solution)
