Full solution

Q. Solve using substitution.\newline2x−5y=−16x=7 \begin{array}{l} 2 x-5 y=-16 \\ x=7 \end{array} \newline(□,□)(\square,\square)
  1. Substitute x=7x = 7: Substitute x=7x = 7 in the equation 2x−5y=−162x - 5y = -16 and then simplify.\newlineCalculation: 2(7)−5y=−162(7) - 5y = -16\newline14−5y=−1614 - 5y = -16
  2. Solve for y: Solve for y in the equation 14−5y=−1614 - 5y = -16.
    Calculation: 14−5y=−1614 - 5y = -16
    −5y=−16−14-5y = -16 - 14
    −5y=−30-5y = -30
    y=−30/−5y = -30 / -5
    y=6y = 6
  3. Write coordinate point: We found that x=7x = 7 and y=6y = 6. Write the solution as a coordinate point.\newlineThe coordinate point is (7,6)(7, 6).
