Question

8(x + 4) + 4(X + 2) = 2X -7

Answer 1

Olá!!  :)

$\sf \\\\ \Rightarrow \ \ 8 \ (x \ + \ 4) \ + \ 4(x \ + \ 2) \ \ = \ \ 2x \ - 7 \\\\ \Rightarrow \ \ 8x \ + \ 32 \ + \ 4x \ + \ 8 \ \ = \ \ 2x \ - \ 7 \\\\ \Rightarrow \ \ 8x \ + \ 4x \ - \ 2x \ \ = \ \ - \ 7 \ - \ 32 \ - \ 8 \\\\ \Rightarrow \ \ 10x \ = \ -47 \\\\ \Rightarrow \ \ \boxed{ \sf \ x \ = \ - \ \frac{47}{10} \ }$

Espero ter ajudado, bons estudos!!  :)
