Grade 9 Equations with Fractions 2
Hi, all. Could you please explain to me how this is done? I don't understand.
Again, when solving an equation with fractions, the very next statement you write -- the next line -- should have no fractions.
| 1 |
| + || 1 |
x − 1
| = || 1 |
2(x − 1)
| Solution. The LCM is 2x(x −1). |
| Here is the cleared equation: |
|x − 1 + 2x || = ||x. |
| Each numerator has been multiplied by those factors of the LCM that are missing from its denominator. The solution follows: |
|2x || = ||1 |
|x || = ||1 |
