Let x=the length of the first film
y=the length of the second film
(1)x=2%2Ay-3
(2)x%2By=132
Sltn.:
substituting (1) to (2), we have,
%282%2Ay-3%29%2By=132
____3%2Ay-3=132
______3%2Ay=135
________y=45
Substituting this value to (1),
x=2%2A45-3
x=87
Therefore, the first film took 87 minutes to finish.
