How to solve system of equations with 3 variables

This gives me all the help I need and everything works properly, very clean and and the steps for the solutions are very easy to understand, can't say anything about the animated solutions because I don't have the premium. Freaking helpful! Although it's annoying that you don't get a deep explaination to a certain step and have to pay for it if you want one, I can show understanding as the app is free and the developers need to make cash somehow.

Much better than photomath in my opinion -- it has the ability to solve a lot more problems, and the steps are very helpful, made graphing SO much quicker. I've been paying for premium for awhile now, and it is worth the money. It is worth it to help understand step by step how to do equations.

Math app app is very helpful to me, I'm enjoying my Engineering mathematic with it, it's great! It helps me do my homework and instead of sitting for 4 hours trying to figure out an equation I use the app and find out in 20 secs, very good, it is a very good app because it helps a lot with my math work, and since stuff is hard to understand I use this and it really does help.
