how did you figure it out

anonymous · Answer

I made really bad typos

anonymous · Answer

Dragonfruit = x - 4
Starfruit = (x - 4) + 2x -5
Rambutan = (x - 4) + 2x

anonymous · Answer

oh never mind

anonymous · Answer

This probably won't make any sense but

anonymous · Answer

You pretty much just have to add it so so it looks like one big equation and then simplify

(x - 4) + 2x

+ (x - 4) + 2x - 5

+ (x - 4) + 2x - 5

+ (x - 4)

+ (x - 4)

+ (x - 4)

anonymous · Answer

So

(x - 4) + (2x) + (x - 4) + (2x) - (5) + (x - 4) + (2x) - (5) + (x - 4) + (x - 4) + (x - 4)
