Answer:
C; to make expressions shorter by simplifying
Explanation:
The reason we combine like terms is to shorten our expressions so they can be easier to be simplified
In the case where we have;
3x-4x+5x + 605 = 9x+ 5x + 60x - 32x
In this case where we want to find the value of x, it is necessary and expident that we combine all the x-values together
Doing this will give us a single value of x
The single value of x can be be evaluated as against the only value which is not having x as a coefficient
