I am a little confused where the sentence stop, could you retype it?

OpenStudy (rizags):

the prompt is screwed up man, rewrite it

OpenStudy (anonymous):

never mind, not sure if the 2nd donny is supposed to be lonny, or what

OpenStudy (rizags):

nEVR mIND, i got it

OpenStudy (rizags):

i'll rewrite the question such that it makes sense

OpenStudy (rizags):

in the sense you have edited it, d=j-5, l=4j, and l=6d. Solving this system by substition, one obtains d=10, j=15, and l=60. Since we are looking for DONNYS house number, its simply 10
