Question

Write five solutions of the equation x+y=7

Answer 1

Answer:

The following are the five solutions:

1. 2 + 5 = 7
2. 1 + 6 = 7
3. 3 + 4 = 7
4. 7 + 0 = 7
5. 6 + 1 = 7

Answer 2

As the equation given the question is having two variables  .

And the number of equations we are provided with is only one.

The total number of equations required to solve a two-variable equation is two.

So, here we will use the trial and error method to solve this problem.

⇒1st solution will be x=1 and y=6, 1+6=7

⇒2nd solution will be x=2 and y=5,2+5=7

⇒3rd solution will be x=3 and y=4,3+4=7

⇒4th solution will be x=4 and y=3,4+3=7

⇒5th solution will be x=5 and y=2,5+2=7
