Question -
Answer -
2y – x = 9
=> x = 2y – 9
Substituting some different values of y, we get their corresponding values of x as shown below:
Now plot the points on the graph and join them
6y – 3x = 21
=> 6y = 21 + 3x
y =
Substituting some different values of x, we get their corresponding values of y as shown below:
Now plot the points on the graph and join them we see that the lines are parallel
The system of equations is inconsistant and therefore has no solution.
