t%2F3+-+3%2Ft+=+0 Start with the given equation


3t%28t%2Fcross%283%29+-+3%2Fcross%28t%29%29+=+3t%280%29 Multiply both sides by the LCD 3t. This will eliminate the fractions.


t%5E2-9+=+0 Distribute and multiply

%28t%2B3%29%28t-3%29=0 Factor the left side


Now set each factor equal to zero:
t%2B3=0 or t-3=0

t=-3 or t=3 Now solve for t in each case


So our answer is
t=-3 or t=3
