    Add 6 to both sides \[\Large 3.5d - 6 \ge 2d + 6\] \[\Large 3.5d - 6\color{red}{+6} \ge 2d + 6\color{red}{+6}\]

    this is done to cancel out the -6 on the left side

    so then\[2d-3.5d \ge2d+12-2d\] Correct?

    well you already did the 3.5d - 2d to get 1.5d

    so you now have \[\Large 1.5d \ge 12\]
