Question

O valor de x na equação x+6/2-x+8/6=x+10/4-1-x/3

Answer 1

Resposta:

[(x+6)/2] - [(x+8)/6] = [(x+10)/4] - [(1-x)/3]

[x/2 + 6/2] - [x/6 + 8/6] = [x/4 + 10/4] - [1/3 + x/3]

(6+x/2) - (8-x/6) = (x+10/4) - (1+x/3)

(36 + 6x/12) - (16 - 2x /12) = (3x + 30/12) - (4 + 4x/12)  *(12)

36 + 6x - 16 - 2x = 3x + 30 - 4 + 4x

20 + 4x = 7x + 26

4x - 7x = 26 - 20

-3x = 6

x = 6/-3

x = -2
