Can someone help me and please leave an explanation

x = 8

Step-by-step explanation:

|20 + 2x| = |4x + 4|

|20 + 2x| = |4 + 4x|

|20 - 2x| = |4|

|-2x + 20| = |4|

-|2x| = |-16|

|-x| = |-8|   =   |x| = |8|

Chow,...!

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
