Identify the solution(s) of the system of equations, if any.

x=1
y=1

a) no solutions
b) (0,0)
c) (1,1)
d) infinitely many solutions

To find the solution(s) of the system of equations, we examine the given equations:

x = 1 ...(Equation 1)
y = 1 ...(Equation 2)

Since Equation 1 states that x equals 1 and Equation 2 states that y equals 1, we can conclude that the only solution to this system of equations is when x = 1 and y = 1.

Therefore, the correct answer is:

c) (1,1)
