Question

3+x/2-(1-x)=x-1/4 me ajudem??

Answer 1

3/1 + x/2 - (1-x)/1 = x/1 - 1/4
12/4 + 2x/4 - 4-4x/4 = 4x/4 - 1/4 
12 + 2x - 4 - 4x = 4x - 1
8 - 2x = 4x - 1
- 2x - 4x = - 1 - 8
(-1) . - 6x =  - 9 . (-1)
6x = 9 
x =  = 1,5
certo?

Answer 2

Resposta:

3/1 + x/2 - (1-x)/1 = x/1 - 1/4

12/4 + 2x/4 - 4-4x/4 = 4x/4 - 1/4  

12 + 2x - 4 - 4x = 4x - 1

8 - 2x = 4x - 1

- 2x - 4x = - 1 - 8

(-1) . - 6x =  - 9 . (-1)

6x = 9  

x =  = 1,5
