$2(3y-1)+3(y-4)=13\\\\2\cdot3y+2\cdot(-1)+3\cdot y+3\cdot(-4)=13\\\\6y-2+3y-12=13\\\\\underbrace{6y+3y}_{9y}\underbrace{-2-12}_{-14}=13\\\\9y-14=13\ \ \ |\text{add 14 to the both sides}\\\\9y=27\ \ \ |\text{divide both sides by 9}\\\\\boxed{y=3}$

If a canoe travels with a speed of A mph for 3 hours, and then with a speed of B mph for the rest of the journey, how long does

mylen [45]

For time-speed-distance problems, you use the relationship
.. speed = distance/time
in any of its various forms.

The distance traveled at A mph is
.. distance = speed * time
.. distance = A*3

The time required for the rest of the journey is
.. time = distance / speed
.. time = (C -3A)/B

The the total time required to travel C miles is the 3 hours for the first part plus the time for the rest of the journey.
.. total journey time = 3 + (C -3A)B . . . . . hours
