Hello Math experts ! I am a novice at 3 equations 4 unknowns. I seem to understand the lectures in the class properly , but when I begin to solve the problems at home myself, I commit errors . Does anyone know of any website where I can get my solutions checked before submitting them for grading? Or any resource where I can get to see a step by step answer ?

I could help if you can be more specific and provide details about 3 equations 4 unknowns. A right computer program would be best option rather than a math tutor. After trying a number of program I found the Algebrator to be the best I have so far come across. It solves any algebra problem that you may want solved. It also explains all the steps (of the solution). You can just write it down as your homework assignment. However, you should use it to learn algebra, and simply not use it to copy answers.

I know a couple of professors who use Algebrator themselves to teach students.

It is really good if you think so. You can find the software here https://algebrahomework.org/laws-of-exponents-and-dividing-monomials.html.
