To solve a system of linear equations with three variables, we basically use the same techniques we used with systems that had two variables. Solve a system of linear equations with three variables. Choose any two of the three equations and eliminate the selected variable. Write the equations in standard form if any coefficients are fractions, clear them. When this is the case, we write and solve a system of equations in order to answer questions about the situation.

Just use the actual equations directly.

Select a suitable variable to eliminate. Write the equations in standard form if any coefficients are fractions, clear them. You are already using the symbolics toolbox, so why would you want to convert the system into a matrix of coefficients and solve it that way? Eq1 = xo2 +xo +xar = 1. If the system has an infinity number. First we add the first and second equation to make an equation with two variables, second we subtract the third equation from the second in order to get another equation with two variables.
