Q. 5
Solve each of the following systems of equations graphically:
3x + 2y = 12
5x – 2y = 4.
Answer :
For equation, 3x + 2y = 12
First, take x = 0 and find the value of y.
Then, take y = 0 and find the value of x.
Now similarly solve for equation, 5x – 2y = 4
Plot the values in a graph and find the intersecting point for the solution.
Hence, the solution so obtained from the graph is (2,3), which is the intersecting point of the two lines.
