What is 8×5y×7=2y+4+2498

Hope this helps!

Step-by-step explanation:

8*5y*7=2y+4+2498

We move all terms to the left:

8*5y*7-(2y+4+2498)=0

We add all the numbers together, and all the variables

8*5y*7-(2y+2502)=0

Wy multiply elements

280y*7-(2y+2502)=0

We get rid of parentheses

280y*7-2y-2502=0

We add all the numbers together, and all the variables

-2y+280y*7-2502=0

Wy multiply elements

-2y+1960y-2502=0

We add all the numbers together, and all the variables

1958y-2502=0

We move all terms containing y to the left, all other terms to the right

1958y=2502

y=2502/1958

y=1+272/979

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.
