ayuda por favor
-2(-x-1)=5+1
-2-x+4(-2x-3)= - 8x+1
6x=-4+x+3+1
4(x-3)-5(x+2)=7(3x-1)+29
$\frac{x-2}{-2} =6$
$\frac{-5-x}{-3}=-2$

Answer 1

A_ -2(-x-1) = 5+1.

2x+2 = 6

2x = 6-2

2x = 4

X = 4÷2

X = 2

B_ -2-x+4(-2x-3) = -8x+1

-2-x-8x-12 = -8x+1

-2-x-12 = 1

-14-x = 1

-x = 1+14

-x = 15

X = -15

C_ 6x = -4+x+3+1

6x = 0+x

6x = x

6x-x = 0

5x = 0

X = 0÷5

X = 0

D_ 4(x-3)-5(x+2) = 7(3x-1)+29

4x-12-5x-10 = 21x-7+29

-x-22 = 21x+22

-x-21x = 22+22

-22x = 44

X = 44÷(-22)

X = -2
