    X=area of Sahara.

    y=area of the Gobi Desert.

    We suggest this system equations:

    x+y=4000000

    x=7y

    solve by susbstitution method.

    (7y) + y=4,000,000

    8y=4,000,000

    y=4,000,000 / 8=500,000

    x=7y

    x=7 (500,000) = 3,500,000

    The area of Sahara=3,500,00 miles².

    The area of the Gobi Desert=500,000 miles²

    To check:

    Te sum of their areas is : 3,500,000 miles²+500,000 miles²=4,000,000 miles²

    Te area of sahara (3,500,000 miles²) is 7 times the area of the Gobi Desert (7*500,000 miles²=3,500,000 miles²).
