original system:
5x-5y=10
3x-2y=2
---
copy and paste the above linear system in standard form into this matrix-method solver:

---
solution:
x = -2
y = -4
---
part A:
---
5x-5y=10
(3x-2y=2) * 2
---
5x-5y=10
6x-4y=4
---
add:
---
11x-9y=14
---
new system:
11x-9y=14
3x-2y=2
---

---
part B:
solution of the new system:
x = -2
y = -4
---
note: the solution of the original system, and the solution of the new system are the same.
