Answer 1

Respuesta:

Explicación paso a paso:

( -1 + 4j )x + 4 - 2j = -2 * (1-j)

( -1 + 4j )x  = -2 * (1-j) - 4 + 2j

( -1 + 4j )x  = -2 + 2j - 4 + 2j = - 6 + 4j

x = ( - 6 + 4j ) / ( -1 + 4j )

x = ( - 6 + 4j ) * ( -1 - 4j ) / [ ( -1 + 4j ) * ( -1 - 4j ) ]

x = [ 6 + 24j - 4j - 16j² ] / [ (-1)² - (4j)² ]

x = [ 6 + 24j - 4j - 16(-1) ] / [ 1 - 16(-1) ]

x = [ 6 + 24j - 4j + 16 ] / [ 1 + 16 ]

x = [ 22 + 20j ] / [ 17 ]

x =  22/17 + 20/17 j
