Answer:
To find the domains you must graph this equation and find the x-coordinates of the points plotted. That's the domain.
Remember, if two points have the same x-coordinate then do not repeat the number when stating the domain. Domain also always must be written in the least to greatest order. Domains must be written with {} enclosing them.
So if the x-coordinates were 4,5,6,4,7,5
You would write the domain as {4,5,6,7}

Answer:
x=55
Step-by-step explanation:
(2x+6)+(x+9)=3x+15
