x-2y = 4
y=3x-22
---
put the system of linear equations into standard form
---
x - 2y = 4
3x - y = 22
---
copy and paste the above standard form linear equations in to this solver:

---
solution:
x = 8
y = 2
---
now by substitution:
---
x - 2y = 4
y = 3x - 22
---
x - 2(3x - 22) = 4
x - 6x + 44 = 4
-5x = -40
x = 8
y = 3*8 - 22
y = 24 - 22
y = 2
---
solution by substitution:
x = 8
y = 2
