Question

A)2x-(x+5)=-3x-9

B)(-2).(x-1)-2x+3=(1).(-x+7-(6-x)

C)(1).(2x+4(-3x-2))=x-17

Answer 1

Respuesta:

A)

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

2x - x - 5 = -3x - 9

x + 3x = -9 + 5

4x = -4

x = -4/4

x = -1

B)

(-2).(x - 1) - 2x + 3 = (1).(-x + 7 - (6 - x) )

-2x + 2 - 2x + 3  = 1(-x + 7 - 6 + x)

-4x + 5 = 1(1)

-4x = 1 - 5

-4x = -4

x = -4/-4

x = 1

C)

(1).(2x+4(-3x-2))=x-17

1(2x - 12x - 8) = x - 17

-10x - 8 = x - 17

-10x - x = -17 + 8

-11x = -9

x = -9/-11

x = 9/11
