Solve the following system using elimination. If a single solution exists, write the solution as an ordered pair. Your answer will be an ordered pair, no solution, or infinitely many solutions


x-y=4
3x-5=2

  • math - ,

    bring y to the other side on first equation so that you will have

    x= y + 4 and substitute y + 4 for x in second equation

    3(y+4) - 5 = 2 and solve

    3y + 12 - 5 = 2

    3y +7 = 2

    3y= -5

    y= -5/3

    plug the answer for y into either equation and solve
