Stones 3

Simiyu and Nasike each collected several 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?

Final Answer:

N =  25
S =  20

Step-by-step explanation:

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

2·(S-5) = N+5
S = N-5

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

Row 2 - Row 1 → Row 2
N-2S = -15
S = 20


S = 20/1 = 20
N = -15+2S = -15+2 · 20 = 25

N = 25
S = 20
