Which 2 order pairs are solutions of y x + 5
5 x 65 is one of many solutions
There are infinitely many solutions, for example, x=-7 and y=5, because -7+5=-2
5 x 10 x 20 is one of many solutions.
There is no equation (or inequality) in the question and so there cannot be any solutions.

no real solutions
1 is the answer
5 x 65 is one of many solutions
Equations can have many solutions. The equation of a straight line, for example, defines all points on the line. Even a simple equation such as x+y=5 can have a variety of solutions (x=1 when y=4, x=2 when y=3 and so on)
There are infinitely many solutions, for example, x=-7 and y=5, because -7+5=-2
None because without an equality sign it is not an equation and so therefore no solutions are possible.
5 x 10 x 20 is one of many solutions.
Some plusses and/or minuses would have assisted. (2x - 5)(x + 6) are factors of 2x2 + 7x - 30, giving solutions for x of 2.5 and -6; (2x + 5)(x - 6) are factors of 2x2 - 7x - 30, giving solutions of -2.5 and 6.
x = 7
