Answer 1

(4x)/(9)+(x-10)/(9)

The numerators of expressions that have equal denominators can be combined.

In this case, (4x)/(9) and ((x-10))/(9) have the same denominator of 9,
so the numerators can be combined.
(4x+(x-10))/(9)

Combine all similar expressions in the polynomial.
(5x-10)/(9)

Factor out the GCF of 5 from 5x-10.
(5(x-2)) / (9)
