-16-4(x+4)=4x please tell me what is x

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

     -16-4*(x+4)-(4*x)=0

Step 1:

(-16 -  4 • (x + 4)) -  4x  = 0

Step 2:

3.1     Pull out like factors :

  -8x - 32  =   -8 • (x + 4)

Step 3:

 -8 • (x + 4)  = 0  

Step 4:

Solve :    -8   =  0

This equation has no solution.

a non-zero constant never equals zero.

Step 5:

Solve  :    x+4 = 0  

Subtract  4  from both sides of the equation:   x = -4

Step 6:

x = negative 4 (-4)

Hope i helped best wishes <333

answer is the third choice:
