Answer 1

Resposta:

-9.

2x = - 18

x = - 18 : 2

x = - 9.

Answer 2

A equação já está montada ↓

$\Box \ \ \boxed{\begin{array}{l}\sf 2x+18=4x+36 \end{array}}\\\\\\\Box \ \ \boxed{\begin{array}{l}\sf 2x-4x=36-18 \end{array}}$

$\Box \ \ \boxed{\begin{array}{l}\sf -2x=18 \end{array}}\\\Box \ \ \boxed{\begin{array}{l}\sf 2x=-18 \end{array}}\\\Box \ \ \boxed{\begin{array}{l}\sf x=\frac{-18}{2} \end{array}}\\\Box \ \ \boxed{\begin{array}{l}\sf x=-9 \end{array}}$
