You can put this solution on YOUR website!
first off this isnt an age problem
but i will do it anyway
(i.e. 37=3(10)+7 so if 3=x and 7=y then 10x+y=37)
a=10x+y
2a=xy
2%2810x%2By%29=10xy
%2820x%2B2y%29=xy
well good luck
5*5=25*2=50 no
6*4=24*2=48 no
2*3=6*2=12 no
2*8=16*2=32 no
2*6=12*2=24 no
2*5=10*2=20 no
3*4=12*2=24 no
3*6=18*2=36 yes wooot i found it
the number is 36
xy=(1/2)(10x+y)
