Answer:

d= -2

Step-by-step explanation:

1. 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

2. Pull out like factors :  -3d - 6  =   -3 • (d + 2)

3.Solve :    -3   =  0

4. the equation has no soluton because A a non-zero constant never equals zero.

5.  then Solve  :    d+2 = 0

6. Subtract  2  from both sides of the equation :  

                 d = -2

 

Answer:

Step-by-step explanation:

 2*d+4-(10+5*d)=0

-3d - 6  =  -3 x (d + 2)

-3   =  0

You know that  d+2 = 0

The you subtract 2 from both sides of the equation as it says in the video :  

which would end up with  -2.

Answer is -2

x is times
