Answer:
-9x + 52/3
Step-by-step explanation:
(−3x+7)+(−6x+10)+(1/3)
Combine −3x and −6x to get −9x.
−9x+7+10+ 1/3
Add 7 and 10 to get 17.
−9x+17+ 1/3
Convert 17 to fraction 51/3
−9x+ 51/3+1/3
Since 51/3 and 1/3 have the same denominator, add them by adding their numerators.
−9x+
51+1/3
Add 51 and 1 to get 52.
-9x + 52/3
