Question

X + 5 Y = 17 5X + Y =13 ,matrices,sove it in carmers method​

Answer 1

Answer:

Cramer's Rule is a method that uses determinants to solve systems of equations that have the same number of equations as variables. Consider a system of two linear equations in two variables.

Find the Determinant of a 2 × 2 Matrix

The determinant of a2 × 2matrix, given

A=[ a b c d ]

is defined as

Notice the change in notation. There are several ways to indicate the determinant, includingdet(A)and replacing the brackets in a matrix with straight lines,|A|.

Using Cramer’s Rule to Solve a System of Two Equations in Two Variables

We will now introduce a final method for solving systems of equations that uses determinants. Known as Cramer’s Rule, this technique dates back to the middle of the 18th century and is named for its innovator, the Swiss mathematician Gabriel Cramer (1704-1752), who introduced it in 1750 in Introduction à l’Analyse des lignes Courbes algébriques. Cramer’s Rule is a viable and efficient method for finding solutions to systems with an arbitrary number of unknowns, provided that we have the same number of equations as unknowns.
