2x+y=3 is a line that has a -2 slope and 6x=9-3x is a vertical line. They will cross at one place. That is (1,2)
Infinitely many, since there is only one equation and one expression.

I suspect the answer depends on the value of t.
There are no real solutions because the discriminant of the quadratic equation is less than zero.
x = -5 x = 2
Through a process of elimination and substitution the solutions are s = 8 and x = 5
Each of the two equations has an infinite number. Simultaneously, they have only one.
