Desmond Lewis · Answer 1

There were 12 birds on Thursday

Step-by-step explanation:

Two equations are needed in a systems of equations.

82=3.5 (b) + 4 (c)

Finding a relation between b and c:

22=b+c

c=22-b

Replacing c with 22-b we get:

82=3.5 (b) + 4 (22-b)

82=3.5b+88-4b

82=88-0.5b

-6=-0.5b

b=12
