Question -
Answer -
x + y = 6 => x = 6 – y
Substituting some different values of y, we get the corresponding values of x as shown under
Now plot the points on the graph and join them
x – y = 2 ⇒ x = 2 + y
Substituting some different values of y, we get the corresponding values of x as shown below:
Now plot the points on the graph and join them
We see that there two lines intersect each other at (4, 2)
x = 4, y = 2
