How many solutions does the system of equations have?

2x = −18y + 16 and x + 9y = 8

To find the number of solutions, we need to solve the system of equations and determine if there is a unique solution, infinitely many solutions, or no solution.

Let's solve the system of equations:

2x = -18y + 16 ---> x = -9y + 8 (equation 1)

x + 9y = 8 (equation 2)

Substitute equation 1 into equation 2:

-9y + 8 + 9y = 8

-9y + 9y + 8 = 8

8 = 8

The equation 8 = 8 is true, which means the original equation 2 has infinitely many solutions.

Therefore, the system of equations has infinitely many solutions.
