Question

5(×-2)-7(×+1)=9(3-2×)

Answer 1

Olá!!!

Resolução!!!

5 ( x - 2 ) - 7 ( x + 1 ) = 9 ( 3 - 2x )

5x - 10 - 7x - 7 = 27 - 18x

5x - 7x + 18x = 27 + 10 + 7

5x + 11x = 27 + 17

16x = 44

x = 44/16 : 2

x = 22/8 : 2

x = 11/4

S = { 11/4 }

Espero ter ajudado!!

Answer 2

Oieee bom dia ; - )

5 ( x -2 ) - 7 ( x + 1 ) = 9 ( 3 -2x )

5x - 10 - 7x - 7 = 27 - 18x

5x - 7x + 18x = 27 + 10 +7

-2x + 18x = 37 + 7

16x = 44

x=44/16 : 2

x= 22/8 : 2

x = 11/4

Resposta = ( 11 / 4 )
