I found out that there are only two solutions because you can only use numbers between 1-15 meaning that you can’t add 0+15 so here are my solutions:
1)6+9+11+12+4+14+7
2)8+7+13+10+6+12+9
Otherwise the other ones would be like this:
1)2+13+7+9+9+12
Which is incorrect because we use nine two times which is not possible
Or:
2)14+1+19+4+12+6
So we have a 19 which is higher that fifteen so this is incorrect
