# Stones 3

Simiyu and Nasike each collected a number of stones in an arithmetic lesson. If Simiyu gave Nasike 5 stones, Nasike would have twice as many stones as Simiyu. If initially, Simiyu had five stones less than Nasike how many stones did each have?

Result

N =  25
S =  20

#### Solution:

2(S-5) = N+5
S = N-5

N-2S = -15
N-S = 5

N = 25
S = 20
