Multiply the whole fraction by seven. You get<span>28n−1=5</span> Gathering the terms,<span>28n=6</span> Dividing by 28, <span>n=3/14</span>
I'm not sure what you mean by LCD, but you could, alternatively,
Add 1/7 to both sides,<span>4n=6/7</span> Multiply the left-hand side by 7/7 (you can do that because it's equal to one, so the equality is preserved),<span>28n/7=6/7</span> Multiply by seven,<span>28n=6</span> And divide by 28, <span>n=6/<span>28</span></span>
