    Hi, welcome to OpenStudy. Do you know how to move the other terms to one side so that way you can isolate the variable m?

    18d – 2m + 9k < 5k + 10 Ok, we have 3 variables. Do you see them? What are the 3 variables?

    The three variables are 2m,9k,5k I think.....

    The variables are m, k, and d. The numbers infront of them are called coefficients.

    OK so do I have to add or subtract the variables?

    So, lets move some variables around to get your answer :) 18d – 2m + 9k < 5k + 10 What happens if we want to move 9k to the left side? Do we have to subtract or add 9k on both sides to remove it?

    We would have to subtract

    Correct! So, lets do it. 18d – 2m + 9k -9k < 5k + 10 -9k Simplify that.

    Ok, now lets move the 18d on both sides: 18d-2m<5k+10-9k Should we add or subtract it? :)

    Correct! So now we have: 18d -18d -2m<5k+10-9k -18d Simplify it :)

    -2m<5k+10-9k-18d

    Great! Now we have to divide by -2 on both sides.

    So it will be -2m<5k+5-9k-9k I think I don't know
