This linear system has one solution: (0,-1).
Step 1: y = 5x - 1
Step 2: 15x - 3(5x - 1) = 3
-15x - 15x + 3 = 3
-30x + 3 = 3
- 3 - 3
----------------------
-30x = 0
-------- ------
-30 -30
x = 0
Step 3: y = 5(0) -1
y = 0 - 1
y = -1
Step 1: y = 5x - 1
Step 2: 15x - 3(5x - 1) = 3
-15x - 15x + 3 = 3
-30x + 3 = 3
- 3 - 3
----------------------
-30x = 0
-------- ------
-30 -30
x = 0
Step 3: y = 5(0) -1
y = 0 - 1
y = -1
