Answer:

See explanation below.

Step-by-step explanation:

Let's say,

x = number of tokens required to play one game of ping pong

y = number of token required play one game of pinball

Using the data given, the system of equations are:

\begin{bmatrix}9x+5y=29\\ 3x+y=7\end{bmatrix}

Solving the system of equations using substitution method will give us:

y=4\:\:\:,\:\:\:x=1

So, one game of ping pong required 1 token, whereas one game of pinball required 4 tokens.
