Question

1 resolva A) 2x-4(x+1)=3(2x+5)​

Answer 1

Resposta:

$\sf{2x-4(x+1)=3(2x+5)}$

$\sf{2x - 4x - 4 = 3(2x + 5)}$

$\sf{2x - 4x - 4 = 6x + 15}$

$\sf{ - 2x - 4 = 6x + 15}$

$\sf{ - 2x - 4 - 6x = 15}$

$\sf{ - 2x - 6x = 15 + 4}$

$\sf{ - 8x = 15 + 4}$

$\sf{ - 8x = 19}$

$\rightarrow\boxed{\boxed{\sf{x = - \frac{19}{8} }}}\checkmark$
