Question

How do I solve for this equation 8(2x+9)=56

Answer 1

Answer:x=-1

Step-by-step explanation:Step by step solution :

Step  1  :

Equation at the end of step  1  :

 8 • (2x + 9) -  56  = 0

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  16x + 16  =   16 • (x + 1)

Equation at the end of step  3  :

 16 • (x + 1)  = 0

Step  4  :

Equations which are never true :

4.1      Solve :    16   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2      Solve  :    x+1 = 0

Subtract  1  from both sides of the equation :

                     x = -1

One solution was found :

                  x = -1
