Make x the subject of the formula x(2+a)=b(x+3)

x=3b/(2+a-b)

Step-by-step explanation:

x(2+a)=b(x+3)

2x+ax=bx+3b

2x+ax-bx=3b

x(2+a-b)=3b

x=3b/(2+a-b)

x( 2 + a ) = bx + 3b

x( 2 + a ) - bx = bx - bx + 3b

x ( 2 + a - b ) = 3b

x ( 2 + a - b ) ÷ ( 2 + a - b ) = 3b ÷ ( 2 + a - b )

x = 3b / 2 + a - b

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.
