can you please help me
8+7r^3/2t^4r

7r^3+8/3t^4r
Need an explanation let me know (: 
yes please

All I did was rearrange the fractions so that the +8 would be on the other side. To get your answer you need put the fractions over each other and start eliminating like terms. Post as far as you can and I'll assist you.
