Question 18926
first, try looking at fractions as just another way to write a division problem.  so that means that the problem is: {{{w/2+7=2h+2}}}
next, to get rid of the fraction, multiply everything by the denominator (the bottom of the fraction) because multiplication is the inverse operation of division:
{{{2(w/2+7)=2(2h+2)}}} and distribute to get {{{w+14=4h+4}}}
anyway, if you have trouble dealing with fractions, work on learning the rules to convert them out of fraction form.
