Question

Batman is 4 times robins age the sum of their ages equals to 45 how old is batman and robin

Answer 1

robins 9 and batmann he old xD (36)

Answer 2

Let's say that Batman's age is b, and Robin's age is r.

We can set up a system of equations as such with the given information:

$b=4r\\b+r=45$

Using substitution, we plug-in 4r from the first equation into b in the second equation to get $5r=45 \\ r=9$.

Now, we plug in the value of r into the first equation to get $b=4(9)=36$.

Thus, Batman is 36 years old, and Robin is 9 years old... A little weird?
