    First, let's work on the left hand side of your inequality, the x-3

    This means, for instance, to see if it can be simplified at all.

    x-3 evaluates to x-3So, all-in-all, the left hand side of your inequality can be written as: x-3Now, let's work on the right hand side of your inequality, the 7

    The right hand side of your inequality can be written as: 7 So with these (any) simplifications, the inequality we'll set out to solve is:

    x-3 7

    Move the - 3 to the right hand side by adding 3 to both sides, like this:

    To the left hand side:

    -3 + 3 = 0 The answer is x To the right hand side:

    7 + 3 = 10

    Now, the inequality reads:

    x>=10

    To isolate the x, we have to divide both sides of the inequality by the other "stuff" (variables or coefficients)

    around the x on the left side of the inequality.

    and this is the final solution to your inequality.

    The answer is 10
