In one volleyball game Naiomi had 3 times as many spikes as Vicki. Together, they had 20 spikes. How many spikes did each Player have? Write and solve a system of equations.

We will use N for the number of spikes Naiomi had and V for Vicki.

N = 3V

N + V = 20

We know N = 3V, so we can use substitution. Plug 3V in for N.

(3V) + V = 20

4V = 20

V = 5

N = 3V = 3 (5) = 15

So Naiomi had 15 spikes, and Vicki had 5 spikes.
