what going none seem to be help with problem

In the first problem, you have no unknown (x). In addition how do you change 0.5 to 0.5? Beside,
0.5 > 20.
Do you have typos? With typos, most tutors do not want to respond.
In the second problem, unless you have a typo,
6d 8d ≠ 14d
6d8d = 2d
I hope this helps. Thanks for asking.
