How many solutions does the system have?

x + y = 5

x + y = 6

- none

- one

- two

-infinite

none

Step-by-step explanation:

to solve this equation we would say that

let

x + y = 5 ... equation 1

x + y = 6 ... equation 2

from equation 2

x + y = 6 ... equation 2

x = 6 - y ... equation 3

substitute for x into equation 1

x + y = 5 ... equation 1

6 - y + y = 5

from here this equation cannot be solved further therefore it has no solution.
