Full solution

Q. Solve using augmented matrices.\newlinex−9y=18x - 9y = 18\newliney=−1y = -1\newline(_____, _____)
  1. Substitute y=−1y = -1: Step 11: Substitute y=−1y = -1 into the first equation.x−9(−1)=18x - 9(-1) = 18x+9=18x + 9 = 18
  2. Solve for x: Step 22: Solve for x.\newlinex+9=18x + 9 = 18\newlinex=18−9x = 18 - 9\newlinex=9x = 9
