I moved all the terms to one side, but I don't know what to do from there on.
Joffan said:Consider the possibilities mod 2, then mod 4, on the two sides of the equation as originally given.
A 3 variable equation is an algebraic equation that contains three variables. This means that there are three unknown quantities in the equation that need to be solved for.
There are many reasons why someone may get stuck on a 3 variable equation. It could be due to a lack of understanding of the concept, a mistake in solving the equation, or a difficult combination of variables.
To solve a 3 variable equation, you can use different methods such as substitution, elimination, or graphing. The specific method to use depends on the equation and the variables involved.
Yes, you can use a calculator to solve a 3 variable equation. However, it is important to check your work and make sure the solution makes sense in the context of the problem.
3 variable equations are commonly used in physics, engineering, and economics to model complex systems and relationships. They are also used in data analysis and statistics to represent multiple variables that affect a certain outcome.
