Question

How to solving linear equations in three variables by cramer's rule?

Answer 1

Using Cramer's Rule to Solve a System of Three Equations in Three Variables. Now that we can find the determinant of a 3 × 3 matrix, we can apply Cramer's Rule to solve a system of three equations in three variables. Cramer's Rule is straightforward, following a pattern consistent with Cramer's Rule for 2 × 2 matrices.

Answer 2

Answer:

by using cramer's rule and equation in which the highest power of the variable is 1 is called the linear equation
