Solve for d.

4d + 7 = -17

is the answer

a: d = -6

b: d = -4.25

c: d = -2.5

or d: d = 2.5

d = -6

Step-by-step explanation:

                    4*d+7-(-17)=0  

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  4d + 24  =   4 • (d + 6)  

Step  2  :

Equations which are never true :

2.1      Solve :    4   =  0

Solving a Single Variable Equation :

2.2      Solve  :    d+6 = 0  

Subtract  6  from both sides of the equation :  

                     d = -6  

             d = -6
