How many solutions does the system of equations have?
x-3y=15 and 3x-9y=5
one
two
infinitely many
none

How many solutions does the system of equations have?
y-5x= -6 and 3y-15x= -12
one
two
infinitely many
none

  1. multiply the 1st by 3 and you have
    3x-9y=45
    3x-9y=5
    There's no way they can both be true. The line sare parallel, so they do not intersect.

    same for #2. Try it and see what happens.
