x=5 and y=6

Let's solve the equation set for y:

-x + y = 1

x + y = 11

=========== add both equations

0 +2y = 12 divide both sides of the equation by 2

y = 6

Let's solve the equation set for x:

-x + y = 1

x + y = 11

=========== subtract both equations

-2x+ 0 =-10 divide both sides of the equation by -2

x = 5

Hence, your solution is: x=5 and y=6.

I made a small plot for you where you can see the solution sets of -x + y = 1 and of x + y = 11. The point both sets intersect is the solution of both sets, namely: x=5 and y=6

xx have:
xx + x x x and x x x xxx
y x x + x and x x y = xx
y = x x x xxx x x (1 + xx = xx
y = 1 + x and xx + x x 11
y = xxx xxx xx = xx
x = xx x xxx x x 5
y x x xxx x = x
