Match the system of equations to the number of solutions it has.(4 points)
3x+6=y and y=−13x−4
y=5x+7 and 3y−15x=18
y=23x−1 and y=23x−2
x−2y=6 and 3x−6y=18
1) No solution - y=5x+7 and 3y-15x=18
2) Infinite number of solutions - y=23x-1 and y=23x-2
3) One solution - 3x+6=y and y=-13x-4
4) Exactly one solution - x-2y=6 and 3x-6y=18
