    Take this in parts:

    First, the phrase, "a number" means we pick an arbitrary variable, let's call it x.

    The product of a number and 7 is 7x.

    8 increased by the product of 7x means we add them together.

    7x + 8

    Finally that entire expression is greater than or equal to -18
    7x + 8 >=-18
