Solve a system of three variables

This system of equations can be solved, it just doesn't have a unique solution. We can try to solve it as if we had just 2 variables.
Sep 11, · In general, you’ll be given three equations to solve a three-variable system of equations. This is similar to how you need two equations to solve a standard system of linear equations. In some.

like Solve: x + 3y = 7, here you say y is a free variable and call y = t then. x = 7 - 3t and t can take any real value like when t= 0, x = 7 ; t = 1, x = 4 etc. Similarly if you have 2 equations in 3 variables, you make one variable free by calling z = t then solve x, .

Here is the detailed strategy for how to solve systems of equations with three variables. Step 1: First, isolate one unknown . x, y, o r z. x,\; y,\; or\; z x, y, or z) in one equation. Step 2: Then substitute the expression for that unknown into the two other equations (not the equation that you already used in step 1.).

Quite right! Idea good, I support.

Unfortunately, I can help nothing. I think, you will find the correct decision.

I think, that you commit an error. I can defend the position. Write to me in PM, we will talk.

I congratulate, excellent idea and it is duly
