There are synchronous exercises in the first volume of mathematics in the first day of junior high school.
Let's assume that A's salary is X and B's salary is Y, then calculate: 4x-5y = 400；; -& gt； x=(400+5y)/4

Get: x= 100+5*y\4.

Now calculate:10x+13y = 6100.

Substitute x:1000+50 * y/4+13y = 6100.

Y=200, then x=350.

A salary is 350, and B salary is 200.
