Ramon was studying pond life in doyle park. in two hours, he counted four more frogs than turtles. the number of crayfish he counted was three more than twice the number of turtles. in total, he counted 54 turtles and crayfish. how many frogs were there?

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
