<PRE><B>Question 699493</B>
&lt;br&gt;&lt;font face=&quot;Tahoma&quot;&gt;This should be a quick one:&lt;br&gt;

{{{5*m+4-7*m=12}}} given&lt;br&gt;

{{{-2*m+4=12}}} combining like terms (m-terms)&lt;br&gt;

{{{-2*m=8}}} subtracting 4 from both sides&lt;br&gt;

{{{m=-4}}} dividing both sides by -2&lt;br&gt;

{{{m=-4}}} solution&lt;br&gt;

I hope this helps!  Keep practicing!  :)&lt;br&gt;
