Question
Use the graphical method to find the value of 'x' for which the expressions `(3x + 2)/(2) and (3)/(4)x - 2`
Advertisements
Solution
Let y = `(3x + 2)/(2)`
The table for y = `(3x + 2)/(2)` is
| X | 2 | 4 | - 2 |
| Y | 4 | 7 | - 2 |
Let y = `(3)/(4) x - 2`
The table for y = `(3)/(4) x - 2` is
| X | 4 | - 4 | 8 |
| Y | 1 | - 5 | 4 |
Now plot the points on a graph and we get the following required graph:
Thus, the value of 'x' is - 4.
