Question

Si A*B=2A-B;A#B=2B - A. Halla el valor de A en (2 * A) # (2 * 3) = (8 * A)

Answer 1

Respuesta:

9

Explicación paso a paso:

( 2 * A ) # ( 2 * 3 ) = ( 8 * A )

( 2 ( 2 ) - A ) # ( 2 ( 2 ) - 3 ) = ( 2 ( 8 ) - A )

( 4 - A ) # ( 1 ) = ( 16 - A )

2 ( 1 ) - ( 4 - A ) = 16 - A

2 - 4 + A = 16 - A

2A = 18

A = 9
