Question

Hola,me ayudan plis :3 es para hoy,no me contesten si no saben o los reporto.​

Answer 1

Respuesta:

a) x - 3 + x = 7 - x - 2

2x - 3 = 5 - x

2x + x = 5+ 3

3x = 8

x = 8/3

b) 1 - 6x = 4x - 3 + 2x

1 - 6x = 6x - 3

-6x - 6x = -3 - 1

-12x = -4

x = 1/3

c ) 5x - 10x - 5 = -12x - 15

-5x - 5 = - 12x - 15

- 5x + 12x = - 15 + 5

7x = -10

x = -10/7

d) x- 1 + 3x = 8x - 1

x + 3x = 8x

4x = 8x

4x - 8x = 0

- 4x = 0

x = 0/-4

x = 0

Espero que te sirva ^^
