  1. 7.2 Two-Variable Linear Systems Elimination method

  2. Solve for (x, y) Given the System, I want to reduce the number of variables. By multiplying both sides of each equation by a number, we can have opposite coefficients to add together to eliminate a variable.

  3. Solve for (x, y) Given

  4. Solve for (x, y) Given Now to find x replace y with 10, in either equation

  5. Solve for (x, y) Given

  6. Airplane Speed An airplane flying into a headwind travels the 1800-mile flying distance between Pittsburgh, Pennsylvania and Phoenix, Arizona in 3 hour hours and 36 minutes. On the return flight, the distance is traveled in 3 hours. Find the airspeed of the plane and the speed of the wind, assuming that both remain constant.

  7. Airplane Speed Airplane travels the 1800-mile in 3 hour hours and 36 minutes. Return the same distance in 3 hours. Find the airspeed, speed of the wind, both constant. Write variable for Speeds Airplane speed r Wind speed w
