Question

Inventa un problema para las siguientes
2x -4=14
-18x +2=2x
13+14x=-15
2.(x-1)=4

Answer 1

2x -4 = 14

2x = 14 + 4

2x = 18

x = 18/2

x = 9

-18x + 2 = 2x

-18x -2x = -2

-20x = -2

x = -2/-20

x = 0.1

13 + 14x = -15

14x = -15 -13

14x = -28

x = -28/14

x = -2

2 . (x -1) = 4

x -1 = 2

x = 2 + 1

x = 3

Espero que te ayude <3
