The equation would be 64.75=34.99+0.48x

64.75=34.99+0.48x now with this equation just subtract 34.99 from both sides

After subtracting you will get 29.76=0.48x

29.76=0.48x now with this equation divide 0.48 on each side to find x

Now since you dive 29.76 by 0.48 you would get the answer 62 minutes

64.75=34.99+0.48x

-34.99 - 34.99

29.76=0.48x

/0.48 / 0.48

63=x
