What is the solution to the equation 2^х+4 – 12 = 20
Please help timed !!!

Step-by-step explanation:Step  1  :

Equation at the end of step  1  :

 2 • (x - 4) -  12  = 0

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  2x - 20  =   2 • (x - 10)

Equation at the end of step  3  :

 2 • (x - 10)  = 0

Step  4  :

Equations which are never true :

4.1      Solve :    2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2      Solve  :    x-10 = 0

Add  10  to both sides of the equation :

                     x = 10

One solution was found :

                  x = 10
