I’m having a hard time understanding your question

To find the answer you need to plug in each individual ordered pair matching up the number with the variable. the answer is (6,2) since if you plug it in the equation becomes 2 = 6 - 4, which ends up 2 = 2. since the final equation is true, then (6,2) must be the answer.
