6t+7t-40=18t
Combine t and 5t to get 6t.
13t-40=18t
Combine 6t and 7t to get 13t.
13t-40-18t=0
Subtract 18t from both sides.
-5t-40=0
Combine 13t and -18t to get -5t.
-5t=40
Add 40 to both sides. Anything plus zero gives itself.
t=\frac{40}{-5}
Divide both sides by -5.
t=-8
Divide 40 by -5 to get -8.
