Question

Rezolvati in R ecuatia :
$\frac{x + 4}{4} - 1.(3) = \frac{x}{8}$
​

Answer 1

(x+4)/4 - (13-1)/9 = x/8

(x+4)/4 - 12/9 = x/8

9(x+4)/36 - 48/36 = x/8

(9x+36)/36 - 48/36 = x/8

(9x-12)/36 = x/8

2(9x-12)/72 = 9x/72

18x-24=9x

18x-9x=24

9x=24

3x=8

x=8/3

Answer 2

$\frac{x + 4}{4} - \frac{4}{3 } = \frac{ \times }{8}$

1,(3)=13-1/9=12/9(simplificam=4/3

aducem toata ecuatia la acelasi numitor si nu mai scriem numitorul

6x+24-32=3x

6x-8=3x

3x=8

x=8/3
