To simplify into 1 fraction, remember, we must make the denominator the same
x/ (x-1 )  - 1/ (2-2x)
= -x/ -(1-x) - 1/(2-2x)    [see the similarity now? ]  [whatever we multiply for the denominator, as long as we multiply to the numerator, it will be ok]
= -2x / -(2-2x)    + 1/-(2-2x)
= (-2x+1 )/ -(2-2x)
=(2x-1)/(2-2x)

Which of these inequalities means that<br> 18 is greater than three times a number?
AnnyKZ [126]
<h3>hello!</h3>

Let's write this verbal phrase as an inequality.

First of all, let the number be n.

"three times n" can be written like so:-

\pmb{3n}

Now, 18 is greater than 3n:-

\pmb{18 > 3n}

Which means 3n is less than 18:-

\bigstar{\boxed{\pmb{3n < 18}}}

<h3>note:-</h3>

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I'll comment and/or edit my answer :)
