Wang Fang and Zhang Li stack paper cranes. Wang Fang's accumulation of paper cranes is 1.5 times that of Zhang Li. If Wang Fang gave Zhang Li four, they would be as many. Now, how much did Zhang Li and Wang Fang fold?
Let Wang Fang put away W and Zhang Li put away Z.
w= 1.5z
w-4=z+4
Substitute 1.5z-4=z+4.
z= 16
w=24
To solve the equation, Wang Fang has 24 stacks and Zhang Li has 16 stacks.
