= %2812x%2B10%29%2F2 becomes,
%2812x%2F2%29+%2B+%2810%2F2%29+=+0 ---------> working eqn
further simplifying,
12x%2F2+%2B+5+=+0
12x%2F2=-5
-10=12x
x=+%28-5%2F6%29 --------------> final answer
To check, go back working eqn & substitute the value of "x",
%28%2812%29%28-5%2F6%29%29%2F2+%2B+10%2F2+=+0
%28-60%2F6%29%2F2+%2B+10%2F2+=+0+
+cross%28-10%2F2%29+%2B+cross%2810%2F2%29+=+0
0=0
Thank you,

%2812x%2B10%29%2F2 Start with the given expression.


%282%286x%2B5%29%29%2F2 Factor out the GCF 2 from 12x%2B10 to get 2%286x%2B5%29


%28highlight%282%29%286x%2B5%29%29%2Fhighlight%282%29 Highlight the common terms.



%28cross%282%29%286x%2B5%29%29%2Fcross%282%29 Cancel out the common terms.


6x%2B5 Simplify.



So %2812x%2B10%29%2F2 simplifies to 6x%2B5.


In other words, %2812x%2B10%29%2F2=6x%2B5
