4a - 3b + 7a
4a and 7a are like terms so you add them together.
4a + 7a = 11a

Answer: 6 pigs and 3 chickens
Step-by-step explanation: you know that each pig has 4 legs and each chicken has 2 legs so start out by saying 9 pigs and 0 chickens which is 36 legs then try 8 pigs and 1 chickens and 8 times 4 = 32 + 2 which is 32 which is more than 30 then notice for every chicken there is you subtract 2 from 36
knowing this we can divide 6 by 2 and get 3 the number of chickens
so 6 pigs and 3 chickens
