Question

Write the solution of the equation x+y=18 . Write your observation​

Answer 1

Answer:

x+y=18 so x=9 and y=9 so 9+9=18

look at this photo like this you have to write more example

Answer 2

Given,

The linear equation $x+y =18$ is given.

To find,

We have to find the solution to the equation $x+y =18$.

Solution,

The solution of the equation$x+y =18$ is (0,18), (1,17).

We can simply find the solution to the equation by assuming the value of one variable and finding the value of another variable.

Let us assume x = 0

      x+y = 18

         y = 18

Let us assume x = 1

    x+y = 18

       y = 17

So, the solution of the equation x+y = 18 are (0,18), (1,17)

We observe that the value of x and y satisfies the equation x+y =18.

Hence, the solution of the equation x+y=18 is (0,18), (1,17).
