Question 1110741: Is the ordered pair (-1,2) a solution of the inequality 2x-y>3? Must show the original substitution of numbers ( ordered pair numbers) into the given inequality. Then simplification of each side without mixing sides. State if it is true or false. Finally state the conclusion about the ordered pair if it is a solution or not a solution.

Substitute the values and test.

2%28-1%29-%282%29%3E3
-
-2-2%3E3
-4%3E3
This is obviously false.
