5l-12=3-4l
Combine 2l and 3l to get 5l.
5l-12+4l=3
Add 4l to both sides.
9l-12=3
Combine 5l and 4l to get 9l.
9l=3+12
Add 12 to both sides.
9l=15
Add 3 and 12 to get 15.
l=\frac{15}{9}
Divide both sides by 9.
l=\frac{5}{3}
Reduce the fraction \frac{15}{9} to lowest terms by extracting and canceling out 3.
