Question

resolver aplicando el método de Cramer
6x -5y +9 =0
3y +4x =13

Answer 1

Respuesta:

Explicación paso a paso:

6x - 5y  = -9

4x + 3y =13

det

[ 6 -5]

[ 4 3 ] = 6·3 + 4·5 = 38

det

[-9 -5]

[13 3 ] = -9·3 + 5·13 = 38

det

[ 6 -9]

[ 4 13] = 6·13 - (-9)·4 = 114

x = 38/38 = 1

y = 114/38 =  3
