Answer 2

Olá!!  :)

1.

$\sf \\\\ \Rightarrow \ \ 7x \ + \ 5 \ = \ 33 \\\\ \Rightarrow \ \ 7x \ = \ 33 \ - \ 5 \\\\ \Rightarrow \ \ 7x \ = \ 28 \\\\ \Rightarrow \ \ x \ = \ \frac{28}{7} \\\\ \Rightarrow \ \ \boxed{ \sf x \ = \ 4}$

2.

$\sf \\\\ \Rightarrow \ \ -4x \ - \ 10 \ = \ -26 \\\\ \Rightarrow \ \ -4x \ = \ -26 \ + \ 10 \\\\ \Rightarrow \ \ -4x \ = \ -16 \\\\ \Rightarrow \ \ x \ = \ \frac{-16}{-4} \\\\ \Rightarrow \ \ \boxed{ \sf x \ = \ 4}$

Espero ter ajudado, bons estudos!!  :)
