Great. A multiple choice question without the choices.
There are an infinite number of ordered pairs. Any point on the straight line which passes through (0,4) and has a gradient of -2 will be an ordered pair for the equation.
These are equations of two straight lines. Provided the equations are not of the same or parallel lines, there can be only one ordered pair. So the answer is - (not are) : (-1, 3).
2x - 2y8 is an expression. It is not an equation and so cannot have a solution.

2x - 3 = 2x - 52x = 2x - 22x - 2x = -20 =/= -2Zero is not equal to -2 so the answer is no solution.
2x plus 3y
There are an infinite number of ordered pairs. (-5, -7) is one pair
(0,4) and (-2, 0)
Dear Questioner its not able to solve two variables for one equation, give one more equation. Thanks
(x, y) = (3, 2)
(10, 2)

y=(-1) x=(2)

x = 12 y = 2 (12,2) satifies the equation
2x - 5y8 is an expression. It is not an equation and so cannot have a solution.
