Question -
Answer -
x + y = 3
=> x = 3 – 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 2x + 5y = 12
2x = 12 – 5y
⇒ x =
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 these two lines intersect each other at (1, 2)
x = 1, y = 2
