Description: How do you check if an ordered pair is a solution to a given equation? You need to plug in the numbers and see what equality results. Watch this video to see a worked example. "Which of the ordered pairs is a "solution of the following equation?" 4x minus one is equal to 3y plus five. So they're gonna, if this is a solution, if this ordered pair is a solution, that means that if x is equal to three and y is equal to two, that that would satisfy this equation up here.
