Y *x =20
y +x =9
rewrite 1st eq. as y = 20/x
subsituute that into 2nd eq.
20/x +x =9
multiply each term by X
20 +x^2 = 9x
subtract 9x from each side:
x^2 - 9x +20 = 0
now factor:
(x-5) (x-4) = 0
solve for x
5-5 = 0
4-4 = 0
so X can be 4 or 5
replace x into equations and solve for Y
so when X = 4, Y = 5
When X = 5, Y = 4
x= 5,4
y = 4,5
The correct answer would be more than 2,000 (approximately 2,205) because on the first he did 30, the second was 33, third was 36, and so on. You would have to make a chart for this, which could be somewhat boring, or you could write it out and do 30+30+3+30+6+30+9, etc for 30 different days, with 30 being for each day and progressively adding 3. Hope this helped!
