Is (3,-2) a solution to 3x+2y=-5

(3, -2) is not a solution to 3x + 2y = -5

Step-by-step explanation:

Step 1:  Check if solution by plugging in 3 for x and -2 for y

3(3) + 2(-2)

9 - 4 = 5

Step 2:  Determine if true

3x + 2y = -5

5 = -5

NOT TRUE

 (3, -2) is not a solution to 3x + 2y = -5

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.
