<p>I had a questions about equations.. So generally, if I had an equation such as</p>

<p>x/3 + x = 5</p>

<p>And I wanted to get rid of the /3 denonminator, I would multiply by 3 to both sides. Like</p>

<p>3 (x/3 + x) = 3(5)</p>

<p>When multiplying by 3 to the left side, the /3 cancels out, but does the 3 then also multiply to the regular x, the one after the plus sign? </p>

<p>I have this question, if you can do--</p>

<p>k+m+(k+m/3) = 348</p>

2

<p>Assuming you mean (x/3) + x = 5, multiplying both sides by 3 yields x + 3x = 15.</p>

<p>Following up on what MITer said, let’s solve the equation.</p>

<p>k+m+(k+m/3) = 348
3[k+m+(k+m/3)] = 3(348)
3(k+m)+(k+m) = 1044
4(k+m) = 1044
k+m = 261 (If they’re asking for what k+m equals)</p>

<p>Correct me if I’m wrong.</p>
