Full solution

Q. Solve.\newline5x+y=−115x + y = -11\newline−2x−y=−1-2x - y = -1\newline(_____, _____)
  1. Add equations to eliminate yy: Step 11: Add the two equations to eliminate yy.5x+y=−115x + y = -11−2x−y=−1-2x - y = -1----------------3x=−123x = -12
  2. Solve for x: Step 22: Solve for x.\newline3x=−123x = -12\newlinex=−12/3x = -12 / 3\newlinex=−4x = -4
  3. Substitute xx back to solve for yy: Step 33: Substitute x=−4x = -4 back into the first equation to solve for yy.5(−4)+y=−115(-4) + y = -11−20+y=−11-20 + y = -11y=−11+20y = -11 + 20y=9y = 9
