b) 1/3x-1=2.(1/3×+1/5)=50
c) 3. (2×-1)+4.(2×+5)=40
d) 4.(×-5)=14-5.(2-×)
​

Answer 1

hola¡

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

3x - 3 + 2 = 4x + 1

3x - 1 = 4x + 1

3x - 4x = 1 + 1

Respuesta: x = -2

b) 1/3x-1=2.(1/3×+1/5)=50

1/3x - 1 = 2 . 1/15 = 50

1/3x - 1 = 2/15 = 50

Respuesta: -2/3x = 2/15 = 50

c) 3. (2×-1)+4.(2×+5)=40

6x - 3 + 8x + 20 = 40

14x + 17 = 40

14x = 40 - 17

x = 23 / 14

Respuesta: 0.575

d) 4.(×-5)=14-5.(2-×)

4x - 20 = 14 - 10 - 5x

4x - 20 = 2 - 5x

4x + 5x = 2 + 20

9x = 22

x = 22/9

Respuesta: 2.4 --> el 4 es infinito
