How many solutions does this linear system have? y is equal to 5 x minus 1 negative 15 x minus 3 y is equal to 3

Substitute y = 5x − 1 into the second equation, −15x − 3y = 3: −15x − 3(5x − 1) = 3. Simplifying gives −30x + 3 = 3, so x = 0; then y = 5(0) − 1 = −1. The system has one solution, (0, −1), which is choice A.
