    The sum of x and 10 equals the sum of 2 times x and 12

    The sum of x and 10 means we add 10 to x:
    x + 10

    2 times x means we multiply x by 2:
    2x

    the sum of 2 times x and 12 means we add 12 to 2x:
    2x + 12

    The sum of x and 10 equals the sum of 2 times x and 12:
    x + 10 + (2x + 12)

    Distribute the parentheses, and we get:
    x + 10 + 2x + 12

    Group like terms:
    (1 + 2)x + 10 + 12
    3x + 22
