If a system has two planes coincident (on the same plane), and the third is parallel to them, how many solutions does it have?

Last Tuesday, Regal Cinemas sold a total of 8500 movie tickets.  Proceeds totaled $64,600.  Tickets can be bought in one of 3 ways:  a matinee admission costs $5, student admission is $6 all day, and regular admissions are $8.50.  How many of each type of ticket was sold if twice as many student tickets were sold as matinee tickets? Given x = regular tickets, y = student tickets, and z = matinee tickets, give the answer in the format (x, y, z) if there is a solution and `no solution` if it cannot be solved.

What is the solution to the following system of equations? y+x=3 x=y+5 Write your answer in the format (#, #) if there is a solution and `no solution` if it cannot be solved. (space between `,` and `#`)

What is the solution to the following system of equations? 2 x + 5 y + 2 z = − 38 − 6 x + y − 7 z = − 12 3 x − 2 y + 4 z = 17 Write your answer in the format (#, #, #) if there is a solution and `no solution` if it cannot be solved. (space between `,` and `#`)
