Right in equation that could be solved to find the number to use Jerry's been doing sit ups, not counting the first day.

Answer 1

Well from what im gathering from your broken english and this ridiculously worded problem, here is how i see it.

15+2x=33

33-15=18, 18/2=9, 15+2(9)=33, 15+18=33, 33=33

x=9
