Question 1011727
When 8 is subtracted from 5 times a number, 12 is obtained. Find the number
<pre>
Put N for the words  "a number"
</pre>
When 8 is subtracted from 5 times N, 12 is obtained.
<pre>
Put 5N for "5 times N"
</pre>
When 8 is subtracted from 5N, 12 is obtained.
<pre>
To subtract 8 from 5N means to put 5N down and then subtract 8 from it.
So we put 5N down and follow it with "minus eight" or -8, and get 5N-8.
So put 5N-8 for "When 8 is subtracted from 5N"
</pre>
5N-8, 12 is obtained.
<pre>
That just means that 5N-8 equals 12, since 12 is what is obtained.
So we just have an = sign between 5N-8 and 12, or
</pre>
5N-8 = 12
<pre>
You finish.
