remember
you can do anything to an equation as long as you do it to both sides
get placeholder by itself
make denomenators same
-1/2t times 3/3=-3/6t
1/3t times 2/2=2/6t
now we have
-3/6t=2/6t-14
minus 2/6t from both sides
-5/6t=-14
times both sides by -6
5t=84
divide both sides by 5
t=16 and 4/5 or 16.8
