Hi Jordan,
I am an an online tutor.I am doing online tutoring for US, UK,UAE ,Japan and Singapore students for the past seven years.I am doing tutoring for basic math, Pre algebra, Algebra1&2, Geometry and precalculus.also I am arranging PSAT, SAT and ACT training sessions.
I am using skype for voice chat and an online whiteboard , where teacher and student share the same screen.Teacher and student can write simultaneously on this board.Your child will get personal attention as I am doing one to one tutoring ( one child at a time). You can do the sessions from your home at your convenient time. I can arrange you two free trial sessions at your convenient time, so that you will get a clear picture of tutoring.I am charging 10$ /hour Please reply me if you are interested. My email ID -tutorrekha@gmail.com
Answer for your question is
5n- (-3n)+6 = 5n+ 3n+ 6 = 8n+ 6
Thank You
