Step-by-step explanation:
wapsi ki Vidya kya hai Hindi mein
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!!!!
Hey There :)
This is because one is half of two. You could also multiply 2 * 0.5= 1, 0.5 represents

and two is the whole number. This is how

of two equals one.
