You may use direct substitution to solve for x and y.
So, x=2 and y=4.
It is irrational, as it's not a number that can be divided into a whole number by another whole number.
If you want to know what is the number of m so first you can add 2 on both sides of equation like : 13 = 5m - 2
+2 +2 ⇒ 13 + 2 = 5m ⇒ 15 = 5m ⇒ 15/5 = m ⇒ 3=m :))
i hope this be helpful
have a nice day
