Answer:

33 3/4 hours or 33 hours and 45 minutes

Step-by-step explanation:

Let h=hours

180=45+45h

Solving for h...

135=45h

h=33.75 or 33 hours and 45 minutes

45 + 45x = 180

subtract 45 from both sides :

45x = 135

divide by 45 to get x by itself :

x = 3

Your answers are :

45 + 45x = 180

and

x = 3
