Lovely proportional reasoning Kathleen! Scaling up and down in tandem, combining pieces that make sense and staying in context. Super!

If 8x = 20 and we want 20x,
There are 2 and a half 8's in 20.
So multiply both sides by 2 1/2
Double then add on half of original
8x + 8x + 4x = 20 + 20 + 10
20x = 50
I'd show it with arrows
