7х+5/3-х +5х+11/х-3=...

Answer 1

( 7х + 5 ) / ( 3 - х ) + ( 5х + 11 ) / ( х - 3 ) = ( 7х + 5 - ( 5х + 11 )) / ( 3 - х ) = ( 2х - 6 ) / ( 3 - х ) = ( - 2•( 3 - х )) / ( 3 - х ) = - 2
Ответ ( - 2 )

Answer 2

(7х+5)/3-х +(5х+11)/х-3= (7х+5)/(3-х) -(5х+11)/(3-x)=(7x+5-5x-11)/(3-x)=(2x-6)/(3-x)=
2(x-3)/(3-x)=-2(3-x)/(3-x)=-2.всьо))
