unklerhaukus · Answer

let the number be nm, where n is the tens digit, and m is the ones digit

unklerhaukus · Answer

$$m>2n$$$$m+n=5$$

Ok thanks

unklerhaukus · Answer

solve the second equation for m and plug into the first equation,

anonymous · Answer

How do you do that

unklerhaukus · Answer

find and inequality for n,

remember that n,m are digits, so they must be natural numbers ,

deduce n, , then find m with the second equation,

i have found two solutions

unklerhaukus · Answer

to solve the second equation for m
m+n=5
take n from both sides
m=5-n
