Answer:
Ryan volunteered 34 hours
Explanation:
Let
x ----> the number of Ryan's hours
y ----> the number of Maddie's hours
we know that
-----> equation A
----> equation B
substitute equation B in equation A and solve for y
![3y+1+y=45\\4y=45-1\\y=44/4\\y=11\ hours](https://img.qammunity.org/2020/formulas/mathematics/middle-school/9phpepo03dpborhte7on5g7nlkko3pu9w6.png)
Find the value of x
![x=3(11)+1\\x=34\ hours](https://img.qammunity.org/2020/formulas/mathematics/middle-school/prhoosab6gsd0ufd3w5c4z4fwtrllfshqz.png)
therefore
Ryan volunteered 34 hours
