            y = 5x - 1
-15x - 3y = 3

               -15x - 3y = 3
     -15x - 3(5x - 1) = 3
-15x - 3(5x) + 3(1) = 3
       -15x - 15x + 3 = 3
                -30x + 3 = 3
                         - 3  - 3
                      -30x = 0
                       -30   -30
                           x = 0

y = 5x - 1
y = 5(0) - 1
y = 0 - 1
y = -1
(x, y) = (0, -1)

This linear system has one solution.
