Answer 4

anyway, back to our equation

x/120 + x/40 = 1

do you know where to go from here?

Answer 5

do you multiply everything by 120? to get rid of the fraction

yup!

Answer 7

x+3x=1?

Answer 8

x + 3x is right

check the right side again

Answer 9

x+3x=120
4x=120

Answer 10

ah, whoops, I think I made a small mistake w/ the numbers > >

should be x/120 + x/80 = 1

(since Tisha builds the box in 80 minutes, not 120)

Answer 14

well, we can still multiply to get rid of the fraction

x/120 + x/80 = 1

let's multiply by 240 instead of 120

2x + 3x = 240

5x = 240
x = 48 min
