Question

If 90n + 23p = 4523, and n and p are both positive integers, what is one possible value of n + p?

Answer 1

n = 50, p = 1

Answer 2

(27,91)
I just graph p = 4523/23 -( 90n/23)

Answer 3

oh n+ p = 51
or n+p = 118

Answer 4

it's funny how I forgot to answer the initial question xD

Answer 5

you will have to test p=1,11,21,31,41,51,61,71,81,91,101,111, 121,...
because 4523-23p=90n=3.3.10.n it's a ten and nine multiple

Answer 6

p=(1,91,181) and n=(50,27,4)
