2x + y = 5
x = y + 7
---
put the system of linear equations into standard form
---
2x + y = 5
x - y = 7
---
copy and paste the above standard form linear equations in to this solver:

---
solution:
x = 4
y = -3
---
now by substitution:
---
2x + y = 5
x = y + 7
---
2(y + 7) + y = 5
2y + 14 + y = 5
3y = -9
y = -3
x = -3 + 7
x = 4
---
solution by substitution:
x = 4
y = -3
