<PRE><B>Question 702279</B>
&lt;br&gt;&lt;font face=&quot;Tahoma&quot;&gt;If I have this correctly, you&#39;re asking for:&lt;br&gt;

2 times&lt;br&gt;

the sum of a number and 7&lt;br&gt;

is 18&lt;br&gt;

We can write this as:&lt;br&gt;

{{{2*(7+x)=18}}} where x is our unknown number.&lt;br&gt;

Then we just need to solve for x:&lt;br&gt;

{{{2*(7+x)=18}}}&lt;br&gt;

{{{14+2x=18}}}&lt;br&gt;

{{{2x=4}}}&lt;br&gt;

{{{x=2}}}&lt;br&gt;

From your question, 2 seems like the definite answer because,&lt;br&gt;

two times the sum of seven and two is eighteen, because:&lt;br&gt;

{{{2*(7+2)=18}}} ???&lt;br&gt;

{{{2*9=18}}} ???&lt;br&gt;

{{{18=18}}} indeed it does&lt;br&gt;

Be careful with the way you ask a question,&lt;br&gt;

because the &quot;what is&quot; at the beginning of your question might be confusing.&lt;br&gt;

I hope this helps!  Keep practicing!  :)&lt;br&gt;
