No, your answer for a) is incorrect.
Always check your solution in the original equation.
2%283%29%2B5=15
6%2B5=15
11=15

2d%2B5=15 Subtract 5 from both sides.
2d=10 Divide both sides by 2.
d=5
Checking,
2%285%29%2B5=15
10%2B5=15
15=15
True, good solution.

20e-4=0 Add 4 to both sides.
20e=4 Divide both sides by 20.
e=4%2F20 Factor out 4 from numerator and denominator.
e=1%2F5
