To get the answer you would have to subtract 23 from both sides and you would get
X+23-23= 63-23
this would leave you with
X= 40
Two-thirds times eighteen is twelve
It would be 4
5 - (- 1)
Would just be 5 - 1 which is 4

Answer:
I do 1 option for you as an example, you need to check the leftover by yourself.
Step-by-step explanation:
for d) y(0) = 0 and y'(pi) =0



Replace
we have
if and only if 
Hence the given solution does not work.
then, d is NOT the correct answer.
