Match the system of equations to the number of solutions it has.
y=5x+7
3y−15x=18
x−2y=6
3x−6y=18
y = 3x + 6
y=−13x−4
y=23x−1
y=23x−2

AAAaannndd the bot gets it wrong yet again!
y=5x+7
3y−15x=18
is equivalent to
y=5x+7
y=5x+6
so there are no solutions
x−2y=6
3x−6y=18
is equivalent to
x−2y=6
x−2y=6
so infinitely many solutions
The last two are obviously 1 solution and no solutions
