x+3y=6
2x+3y=18
---
put the system of linear equations into standard form
---
x+3y=6
2x+3y=18
---
copy and paste the above standard form linear equations in to this solver:
https://sooeet.com/math/system-of-linear-equations-solver.php
---
solution:
x = 12
y = -2
---
by substitution:
---
x + 3y = 6
x = 6 - 3y
---
2(6 - 3y) + 3y = 18
12 - 6y + 3y = 18
-3y = 6
y = -2
---
x = 6 - 3y
x = 6 - 3*(-2)
x = 12
---
solution by substitution:
x = 12
y = -2
