Q. Solve using augmented matrices.\newline5x8y=145x - 8y = -14\newlinex=10x = 10\newline(_____, _____)
  1. Substitute x value: First, let's substitute the value of xx into the first equation to simplify it. Since x=10x = 10, we replace xx in the equation 5x8y=145x - 8y = -14.\newlineCalculation: 5(10)8y=145(10) - 8y = -14\newline508y=1450 - 8y = -14
  2. Isolate y: Next, we need to isolate y. To do this, subtract 5050 from both sides of the equation.\newlineCalculation: 8y=1450-8y = -14 - 50\newline8y=64-8y = -64
  3. Solve for y: Now, solve for y by dividing both sides by 8-8.\newlineCalculation: y=64/8y = -64 / -8\newliney=8y = 8
