Solve using the elimination method.Show work.If system has no solution state this or infinite solution
8x+10y=-34
16x-5y=-43

  • Intermediate Algebra -

    Note that, because of the first equation, 16x + 20y = -68.

    Substitute -68 -20y for 16x in the second equation.

    -68 -20y -5y = -43
    -25y = 25
    y = -1

    8x -10 = -34
    8x = -24
    x = -3
