Question 928203: How would I solve x +5y=18 and 3x+2y=-11 by the elimination method
thanks

You can put this solution on YOUR website! x + 5y = 18
3x + 2y = -11
---
put the system of linear equations into standard form
---
x + 5y = 18
3x + 2y = -11
---
copy and paste the above standard form linear equations in to this solver:

---
solution:
x = -7
y = 5
---
now by elimination:
---
-3(x + 5y = 18)
3x + 2y = -11
---
-3x - 15y = -54
3x + 2y = -11
---
add the two equations:
---
-13y = -65
y = 5
x + 5y = 18
x = 18 - 5y
x = 18 - 5*5
x = -7
---
solution by elimination:
x = -7
y = 5
