An equation is shown below: 6(2x - 11) + 15 = 21

Write the steps you will use to solve the equation and explain each step.

x=6

Step-by-step explanation:

Let's solve your equation step-by-step.

6(2x−11)+15=21

Step 1: Simplify both sides of the equation.

6(2x−11)+15=21

(6)(2x)+(6)(−11)+15=21(Distribute)

12x+−66+15=21

(12x)+(−66+15)=21(Combine Like Terms)

12x+−51=21

12x−51=21

Step 2: Add 51 to both sides.

12x−51+51=21+51

12x=72

Step 3: Divide both sides by 12.

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.

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
