Question

resolver las siguientes ecuaciones y comprobarlas .

A) 8( x-3 )=2







COMPROBACION:






B) (x-5 ) -6 ( x+4 ) = 0






COMPROBACION:






ayuda plis con su respectiva comprobacion.

Answer 1

8 ( x - 3 ) = 2

8x - 24 = 2

8x = 2 + 24

8x = 26

x = 26 / 8

x = 13 / 4

COMPROBACION =

8 ( x - 3 ) = 2

8 ( 13/4 - 12/4 ) = 2

8 ( 1/4 ) = 2

8/4 = 2

2 = 2

( x - 5 ) - 6 ( x + 4 ) = 0

( x - 5 - 6x - 24 ) = 0

( x - 6x ) = ( 5 + 24 )

- 5x = 29

x = 29 / - 5

x = - 29 / 5

COMPROBACION =

( x - 5 ) - 6 ( x + 4 ) = 0

( - 29/5 - 5 ) - 6 ( - 29/5 + 4 ) = 0

( - 29/5 - 25/5 ) - 6 ( - 29/5 + 20/5 ) = 0

- 54/5 - ( - 174/5 + 120/5 ) = 0

( 174/5 - 54/5 - 120/5 ) = 0

( 174/5 - 174/5 ) = 0

0 = 0
