Answer:
All real numbers
Step-by-step explanation:
12(x+3)=4(2x+9)+4x
First you are going to distibute 12 and 4 into the paranthese to get:
12x+36=8x+36+4x
Next you are going to combine like terms (the 8x and 4x) to get:
12x+36=12x+36
Since both sides of the equation equal each other this means that x can equal any real number since they always equal each other.
