How many solutions does this system have?
2x+3y=-3
3x+ 5y=-9

Step-by-step explanation:

2x + 3y = -3                     3x + 5y = -9

3y = -2x - 3                      5y = -3x - 9

y = -2/3x - 1                       y = -3/5x - 9/5

slope = -2/3                      slope = -3/5

y int = -1                             y int = -9/5

to find the answer, u must compare the slopes and the y intercepts.

if they have the same slope and different y int's, then there is no solution

if they have the same slope and the same y int's, they have infinite solutions

if they have different slopes and different y int's, they have 1 solution

so this system has 1 solution <===

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
