Solve each of the following systems of equations graphically:
2x – 3y + 13 = 0
3x – 2y + 12 = 0.
We can rewrite the equations as:
2x – 3y = - 13
& 3x – 2y = - 12
For equation, 2x – 3y = - 13
First, take x = 0 and find the value of y.
Then, take y = 0 and find the value of x.
x | 0 | - 13/2 |
y | 13/3 | 0 |
Now similarly solve for equation, 3x – 2y = - 12
x | 0 | - 4 |
y | 6 | 0 |
Plot the values in a graph and find the intersecting point for the solution.
Hence, the solution so obtained from the graph is ( - 2,3), which is the intersecting point of the two lines.
