    The answer is: Jacob Johnson should cultivate 400 acres of corn and 100 acres of wheat.

    Explanation:

    x = corn acre; y = wheat acre

    Step 1:

    x + y = 500

    42x + 30y = 19,800

    Step 2:

    Multiply (x + y = 500) times - 30; - 30x - 30y = - 15,000

    Step 3:

    42x + 30y = 19,800

    -30x - 30y = - 15,000

    Step 4:

    (42x - 30x) + (30y - 30y) = 19,800 - 15,000; 12x = 4,800

    Step 5:

    x = 4,800/12; x = 400

    Step 6:

    400 + y = 500; y = 100
