Solve each of the following systems of equations graphically:
3x + 2y = 4,
2x – 3y = 7.
For equation, 3x + 2y = 4
First, take x = 0 and find the value of y.
x | 0 | 4/3 |
y | 2 | 0 |
Now similarly solve for equation, 2x - 3y = 7
x | 0 | 7/2 |
y | - 7/3 | 0 |
Plot the values in a graph and find the intersecting point for the solution.
Hence, the solution so obtained from the graph is (2, - 1), which is the intersecting point of the two lines.
