Grade 9 Equations with Fractions 2
Hi, all. Could you please explain to me how this is done? I don't understand.

2x  +  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
2 
Again, when solving an equation with fractions, the very next statement you write  the next line  should have no fractions.
Thanks. :)

This is very similar to your other post.
They multiplied both sides of the equation by the least common denominator, which in this case would be $\displaystyle 2x(x1).$
