x + y = 4, x - y = 6 the solutions are: x = 5, y = -1

x + y = 4;

x = 6 + y;

Substitute x = 6 + y:

(6 + y) + y = 4;

6 + 2y = 4;

2y = 4 - 6; 2y = -2; y = -1;

Plug y = -1:

x + y = 4;

x - 1 = 4; x = 4 + 1; x = 5

x + y = 4;

x = 6 + y;

Substitute x = 6 + y:

(6 + y) + y = 4;

6 + 2y = 4;

2y = 4 - 6; 2y = -2; y = -1;

Plug y = -1:

x + y = 4;

x - 1 = 4; x = 4 + 1; x = 5
