-3x + 6y = -27
x = -1
---
put the system of linear equations into standard form
---
-3x + 6y = -27
x = -1
---
copy and paste the above standard form linear equations in to this solver:

answer:
x = -1
y = -5
---
now by substitution:
---
-3x + 6y = -27
x = -1
---
-3*-1 + 6y = -27
6y = -27 - (-3*-1)
y = ( -27 - (-3*-1) )/6
y = ( -27 - 3 )/6
y = ( -30 )/6
y = -5
---
answer by substitution:
x = -1
y = -5
