我的一道题不会做。我的朋友小明帮助我做了出来 用英语怎么说

my friend worked out a problem which i don't know how to deal with

My friend Xiaoming helped me to work out a problem that I couldn't solve myself .

when I meet problems which I cannot work out, firstly I will ask my friends for help. For example, everytime I come across math trouble, after thinking but even having no result, I would ask my best friend Li lei. He is a clever boy who is good at math.
