Solution - Linear equations with one unknown

d=2
d=-2

Step by Step Solution

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                     2*d+4-(10+5*d)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   -3d - 6  =   -3 • (d + 2) 

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

 2.1      Solve :    -3   =  0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

 2.2      Solve  :    d+2 = 0 

 
Subtract  2  from both sides of the equation : 
 
                     d = -2

One solution was found :

                   d = -2
