Question

_2(8×-5)=9*+5-2(9+x)
$4( - 6x - 7 ) = 4 \times + 10 - 2(1 + \times )$
​

Answer 1

Explicación paso a paso:

A) -2(8x-5)=9×+5-2(9+x)

-16x+10=45-18-2x

-16x+10=27-2x

-16x+2x=27-10

-14x=17

x=- 17/14

B) 4(-6x-7)=4×+10-21(1+x)

-24x-28=4-10-21-21x

-24x-28=-27-21x

-24x+21x=-27+28

-3x=1

x= -1/3
