Full solution

Q. Solve using substitution.\newline5x+6y=−145x + 6y = -14\newlinex=8x = 8\newline(_____, _____)
  1. Substitute x=8x = 8: Substitute x=8x = 8 into the first equation 5x+6y=−145x + 6y = -14 and then simplify.\newlineCalculation: 5(8)+6y=−145(8) + 6y = -14\newline40+6y=−1440 + 6y = -14
  2. Solve for y: Solve for y in the equation 40+6y=−1440 + 6y = -14.\newlineCalculation: 6y=−14−406y = -14 - 40\newline6y=−546y = -54\newliney=−54/6y = -54 / 6\newliney=−9y = -9
  3. Write coordinate point: We found that x=8x = 8 and y=−9y = -9. Write the solution as a coordinate point.\newlineThe coordinate point is (8,−9)(8, -9).
