Full solution

Q. Solve.\newlinex=−7x = -7\newline−3x−7y=−14-3x - 7y = -14\newline(_____, _____)
  1. Substitute x=−7x = -7: Substitute x=−7x = -7 into the equation −3x−7y=−14-3x - 7y = -14.\newlineCalculation: −3(−7)−7y=−14-3(-7) - 7y = -14\newline21−7y=−1421 - 7y = -14
  2. Isolate y: Isolate yy.\newlineCalculation: 21−7y−21=−14−2121 - 7y - 21 = -14 - 21\newline−7y=−35-7y = -35
  3. Solve for y: Solve for y.\newlineCalculation: y=(−35)/−7y = (-35) / -7\newliney=5y = 5
