You can put this solution on YOUR website! x + y = -4
x-y = -6
---
put the system of linear equations into standard form
---
x + y = -4
x - y = -6
---
copy and paste the above standard form linear equations in to this solver:

---
solution:
x = -5
y = 1
---
now by addition method (aka elimination method):
---
x + y = -4
x - y = -6
---
add the two equations:
---
2x = -10
x = -5
x + y = -4
-5 + y = -4
y = -4 + 5
y = 1
---
solution by addition method (aka elimination method):
x = -5
y = 1
