You can put this solution on YOUR website!
6x - 21 = 3y
y = -2x + 13
---
put the system of linear equations into standard form
---
6x - 3y = 21
-2x - y = -13
---
copy and paste the above standard form linear equations in to this solver:

solution:
x = 5
y = 3
---
system matrix
6 -3
-2 -1
---
inverse of system matrix
0.083333333 -0.25
-0.16666667 -0.5
---
determinant of system matrix = -12
