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.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
