Multiplying both sides by negative 1, you get z is equal to negative 4. So we're done. Let's verify that these solutions, or the solution of x is negative 1, y is equal to 2, z is equal to negative 4, actually satisfies

Incredibly helpful and very accurate, the fact that it shows the solucion with steps is just amazing. It even has the answers to many textbooks with the paid version, i recommend. This is agreat app, it's an efficient app too.

Espically for remote learning, very easy to use and clear with explanations, honestly this app is good! Some who say it isn't. I do think it's a good app but for quick calculations, for exams your mind is the best so my opinion is that this app should only used for quick calculations but not for exams where you should sit and think and use your mental math or bye working your self, by doing handwritten work because obviously app cannot be used in exam halls.

Would recommend it to everybody who has some quick syllabus completing to do and doesn't know solutions to some problems! Tho I do hope that you'll add word problem solving in the near future as well.
