Question 12584
If you really don't like fractions, then multiply both sides by the denominator which is 2, and get rid of it:


{{{A/2 + 5 = 10}}}


{{{2*(A/2) + 2*5 = 2*10}}}


The 2 divides out in the first term, leaving:
{{{A + 10 = 20}}}


Now just subtract 10 from each side:
{{{A+10-10 = 20-10}}}
{{{A= 10}}}
