Answer:
14
Step-by-step explanation:
Set up the two equations:
5.5x + 7y = 217
x + y = 34
7x + 7y = 238
5.5x + 7y = 217
1.5x = 21
x = 14

What is a system of equations?
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
An animal shelter spends $5.50 per day to care for each bird and $7.00 per day to care for each cat.
Gianna noticed that the shelter spent $217.00 caring for birds and cats on Friday.
Gianna found a record showing that there were a total of 34 birds and cats on Friday.
Set up the two equations:
5.5x + 7y = 217----a
x + y = 34-------b
multiply by 7 on both the sides of equation b
7x + 7y = 238
Solving equation a
5.5x + 7y = 217
1.5x = 21
x = 14
There were 14 birds at the shelter on friday.
