10 is the initial value, found when x=0. I don't know what you are measuring by "0" and "10" here, so can't be more specific.
Get one x+y=3 to y=x+3 and plug it into x-y=1 and you get x-(x+3)=1. Destitute the x and solve. Once you get what x equals plug it to to either equation for the value of x and solve for y
