Question 1189810
x = price of a ping pong token.
y = price of a pinball token.


9x + 5y = 29
3x + y = 7


multiply both sides of the second equation by 3 and lave the first equation as is to get:


9x + 5y = 29
9x + 3y = 21


subtract the second equation from the first to get:


2y = 8


solve for y to get y = 4
use y = 4 to solve for x to get x = 1


replace x and y with 4 and 1 in the original equations to get:
9x + 5y = 29 becomes 9 + 20 = 29
3x + y = becomes 3 + 4 = 7
this confirms the values are good.


you were asked to write a system of equation to model the situation.
that solution is:


9x + 5y = 29
3x + y = 7
x = price of a ping pong token.
y = price of a pinball token.


i went a little further and solved it, but that's not what they asked.
