Answer 2

$\Box \ \ \boxed{\begin{array}{l}\sf 3x-4-10-4x=6+3x-4 \ ?? \end{array}}\\\\\\\Box \ \ \boxed{\begin{array}{l}\sf -x-14=2+3x \end{array}}\\\Box \ \ \boxed{\begin{array}{l}\sf -x-3x=2+14 \end{array}}\\\Box \ \ \boxed{\begin{array}{l}\sf -4x=16 \end{array}}\\\Box \ \ \boxed{\begin{array}{l}\sf 4x=-16 \end{array}}\\\Box \ \ \boxed{\begin{array}{l}\sf x=\frac{-16}{4} \end{array}}\\\Box \ \ \boxed{\begin{array}{l}\sf x=-4 \ \checkmark \end{array}}$

Resposta correta;

x=-4

Prova Real;

$\Box \ \ \boxed{\begin{array}{l}\sf 3x-4-10-4x=6+3x-4 \end{array}}\\\\\\\Box \ \ \boxed{\begin{array}{l}\sf -x-14=2+3x \end{array}}\\\Box \ \ \boxed{\begin{array}{l}\sf -14-2=3x+x \end{array}}\\\Box \ \ \boxed{\begin{array}{l}\sf -16=4x \end{array}}\\\Box \ \ \boxed{\begin{array}{l}\sf -16=-4-4-4-4 \end{array}}\\\Box \ \ \boxed{\begin{array}{l}\sf -16=-16 \end{array}}\\\Box \ \ \boxed{\begin{array}{l}\sf \rightarrow \ =-16+16 \end{array}}$

$\Box \ \ \boxed{\begin{array}{l}\sf \rightarrow \ =\boxed{\begin{array}{l}\sf 0\end{array}} \end{array}}$

Então, Resposta Correta;

$x=-4$
