The method of solving a
Explanation of Solution
Let, the linear equation is:
To solve algebraically:
We have,
Hence, the solution is:
To solve graphically:
We have,
Hence, in terms of graph we have to find out the intersection of
The intersection of the two graphs will give the solution.
Now,
Calculation of graph:
Consider,
Values of x | Values of y |
0 | -4 |
1 | -2 |
2 | 0 |
3 | 2 |
4 | 4 |
Using the above table the graph can be plotted.

Calculation of graph:
Consider,
Values of x | Values of y |
0 | 6 |
1 | 6 |
2 | 6 |
3 | 6 |
4 | 6 |
Using the above table the graph can be plotted.
Graph:
Plotting the both the graphs on the same co-ordinate plane:
Interpretation:
The both graphs intersect at
Conclusion:
Hence, the solution is
