Xiaohong’s joke is to solve a linear equation of two variables 1: mx+ny=16, 2:nx+my=1. Xiaohua mistakenly formed equation 1 into x=-1, y=3, Xiaohong Get equation 2 wrong
Solution: From the known: -m+3n=16
-n+3m=1
The solution is m=19/8
n=48/8
Put m=19/8 into mx+ny=16; nx+my=1
n=48/8
Solve for x=?
y=?
