Unless this is some kind of alien math, there is no such rule as "no negative variables".


17-a=17 ---> -a = 17-17=0 ---> -a = 0 ---> a = 0

Hope the solution helped. Sometimes you need more than a solution. Contact fcabanski@hotmail.com for online, private tutoring, or personalized problem solving (quick for groups of problems.)
