Need the equation in its exponential form.

For this case we have that by properties of logarithm that:

is equivalent to the following expression:

We have the following expression:

Then, according to the property we have:

Option A

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
