Answer:

one solution: (0, –1)

Step-by-step explanation:

we have

$y=5x-1$ ----> equation A

$-15x-3y=3$ ----> equation B

isolate the variable y in the equation B

$3y=-15x-3$

$y=-5x-1$ ----> equation C

Compare equation A and equation C

The equations are different

The slopes are different ( are not parallel lines)

therefore

The system has one solution

Solve the system

equate the equation A and equation C and solve for x

$5x-1=-5x-1$

$5x+5x=-1+1$

$x=0$

Find the value of y

$y=5(0)-1=-1$

The solution is the point (0,-1)
