Solve for w.<br> 8(w+2) = 40
AleksAgata [21]

Answer:

  w = 3

Step-by-step explanation:

 8 • (w + 2) -  40  = 0

Pulling out like terms :

3.1     Pull out like factors :

  8w - 24  =   8 • (w - 3)

Equation at the end of step  3  :

 8 • (w - 3)  = 0

Step  4  :

Equations which are never true :

4.1      Solve :    8   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2      Solve  :    w-3 = 0

Add  3  to both sides of the equation :

                     w = 3

One solution was found :

                  w = 3
