Answer:

Step-by-step explanation:
Starting with :
m g + r g = 2 H
extract "g" as a common factor on the left of the equal sign:
g (m + r) = 2 H
Now, in order to solve for "g" , divide both sides of the equal sign by the binomial (m + r):
g = (2 H )/(m + r)

I believe the equation would be
160+0.2y
Because 160 deer and you round the 20% into a decimal point.
5c+10a=3570
c+a=512
...
a=512-c
so ...
5c + 10(512-c)=3570
