Question

rezolvati in r ecuatia x+4=3(3x-2)​

Answer 1

Răspuns:

x = 1,25 ∈ R ​

Explicație pas cu pas:

x + 4 = 3(3x - 2)

x + 4 = 9x - 6

x - 9x = - 6 - 4

- 8x = - 10

x = -10/-8

x = 1,25 ∈ R ​

Answer 2

$\bf x+4=3 \cdot(3x-2)$

$\bf x+4=9x-6$

$\bf x+4 + 6=9x$

$\bf 10=9x - x$

$\bf 10=8x$

$\bf x= \dfrac{10}{8}$

$\bf x= \dfrac{ \not10}{ \not8}$

$\boxed{\bf x= \dfrac{5}{4}}$
