raketka [301]

Let named variables as you said g- guinea pigs and c- chinchillas
System of equation is:

First is: c+ g = 60,005
Second is: c= 2g+5

When we replace second in first we get:

2g+5+g = 60,005 => 3g+5= 60,005 => 3g= 60,000

g=60.000/3 = 20,000 => g=20,000

When this result we replace in the second equation we get

c= 2 * 20,000 +5= 40,000+5 = 40,005

c= 40,005

Good luck!!!!
