Get either the y or x by itself:
x=11-y
Then substitute 11-y in for any x variable:
(11-y) - y = -7
11-2y = -7
-2y = -18
Divide by -2
y = 9
Then plug 9 into the first equation:
x + 9 = 11
x = 2

remedy between the equations for x or y, then change it into the different equation: 7x + y = 10 y = 10 - 7x 2y + 5x = 11 2(10 - 7x) + 5x = 11 20 - 14x + 5x = 11 -9x = -9 x = a million y = 10 - 7x y = 10 - 7(a million) y = 10 - 7 y = 3

x=11-y and x =-7+y is there any number that represents what x or y should be?

x+y=11
Isolate one variable
x=11-y
x-y=-7
(11-y)-y=-7
11-2y=-7
18=2y
y=9
So, x=2
