Full solution

Q. Solve using substitution.\newline−4x+5y=−14-4x + 5y = -14\newlinex=−9x = -9\newline(_____, _____)
  1. Substitute x=−9x = -9: Substitute x=−9x = -9 into the first equation –4x+5y=–14–4x + 5y = –14 and then simplify.\newlineCalculation: –4(−9)+5y=–14–4(-9) + 5y = –14\newline 36+5y=–1436 + 5y = –14
  2. Solve for y: Solve for y in the equation 36+5y=−1436 + 5y = -14.
    Calculation: 5y=−14−365y = -14 - 36
    5y=−505y = -50
    y=−50/5y = -50 / 5
    y=−10y = -10
  3. Write coordinate point: We found that x=−9x = -9 and y=−10y = -10. Write the solution as a coordinate point.\newlineThe coordinate point is (−9,−10)(-9, -10).
