Question 870589

please help,I need to find n,  5 n + 1 divided by 2 - 3 = 20 there is a line under the 5n+1 and the 3 is under the 5n+1, then -3=20, I need to see the workings for this formula, help would be appreciated
<pre>
{{{(5n + 1)/2 - 3 = 20}}}
5n + 1 - 6 = 40 ------- Multiplying by LCD, 2
5n - 5 = 40
5n = 45
{{{n = 45/5}}}, or {{{highlight_green(9)}}}
You can do the check!!
