Best way to solve would be using Elimination Method. Here's how to solve. 9x + 8y = 15 9x + 8y = 30 To cancel out a variable multiply one equation with -1. 9x + 8y = 15 -1(9x + 8y = 30) Distribute. 9x + 8y = 15 -9x - 8y = -30 Add both equations together. 0 = -15 So no solution would be your answer. I hope this helps love! :)
