The spiral notebook contains 30 more sheets than the memo one, so we have the first equation:
s sheets  m sheets = 30 sheets
or s  m = 30 (1)
(1) ⇒ 3s  3m = 90
"The total number of sheets of paper in 3 spiral notebooks and 5 memo books is 810", which means we have another equation:
3*s sheets + 5*m sheets = 810 sheets
or 3s + 5m = 810.
3s  3m = 90
3s + 5m = 810
From this set of equations, you can solve for s and m:
s = 120
m = 90
There are 120 sheets in a spiral notebook and 90 sheets in a memo notebook.
Hope this helps~
