Algebra

This a great app for those who would like to touch up on algebra, it doesnt seem to have the complete function I was looking for, for example, 2x+1/2x+1/4x=99, I cant enter the fractions, if you can they can help me out with this ill give five stars.
P. S. I had difficulty using this app right away and their support is excellent
