Question

How many solutions does the system have?

x + y = 5
x + y = 6
- none
- one
- two
-infinite

Answer 1

none

Explanation:

A on edge

Answer 2

none

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.
