The cost of 2 televisions and 3 DVD players is $1,421. The cost of 1DVD player is half the cost of 1 television. What is the cost of 1 television?

    $X = Cost of each TV.
    $X/2 = Cost of each DVD.

    2x + 3x/2 = 1421
    Multiply both sides by 2:
    4x + 3x = 2842
    7x = 2842
    X = $406 = Cost of 1 TV.
