Question

Tìm x

-35 - (x+7) = 250 + 6(x-93)

Answer 1

        - 35  - ( x+ 7 ) = 250 + 6( x- 93 )

<=>   -35 - x - 7       =  250 + 6x - 558

<=>                 - 7x  =  -226

<=>                     x  = 38

OK

Answer 2

-35-(x+7)=250+6*(x-93)

=>-35-x-7=250+6x-558

=>-42-x=6x-308

=>-42+308=x+6x

=>266=7x

=>x=266:7

=>x=38

k mh nha

Answer 3

-35 - (x+7) = 250 + 6(x-93)

<=>-(x+42)=2(3x-154)

=>-x-42=6x-308

=>-7x=-266

=>x=(-266):(-7)

=>x=38
