Question

3(x+1)-2(x-1)=-(x+5)​

Answer 1

Resposta:

x = -5

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

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

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

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

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

$\sf{x + 5 = - x - 5}$

$\sf{x + 5 + x = - 5}$

$\sf{x + x = - 5 - 5}$

$\sf{2x - 5 - 5}$

$\sf{2x = - 10}$

$\sf{10 \div 2}$

$\rightarrow \boxed{\sf{x = - 5 }}$
