You can put this solution on YOUR website!
m = my age now
d = my daughter's age now
m+=+26+%2B+d
add -d to both sides
m+-+d+=+26
multiply both sides by 2
2m+-+2d+=+52
3m+%2B+2d+=+103
------------------
add these equations
5m+=+155
m+=+31
m+=+26+%2B+d
31+=+26+%2B+d
d+=+31+-+26
d+=+5
I am 31 and my daughter is 5

3m+%2B+2d+=+103
3%2A31+%2B+2%2A5+=+103
93+%2B+10+=+103
103+=+103
OK
