↬ Hey cherry, este exercício é bem fácil, vamos apenas dividir. Simples, não?!

$\begin{gathered}\qquad\LARGE\red{\boxed{\red{\boxed{\begin{array}{rcl}\mathbf{\red{2x = - 40}}\end{array}}}}}\end{gathered}$

↬ Divida os membros da equação por 2.

$\begin{gathered}\qquad\LARGE\red{\boxed{\red{\boxed{\begin{array}{rcl}\mathbf{\red{2x \div 2 = - 40 \div 2}}\end{array}}}}}\end{gathered}$

↬ Lembrado que, absolutamente qualquer número dividido por ele mesmo será igual à um.

$\begin{gathered}\qquad\LARGE\red{\boxed{\red{\boxed{\begin{array}{rcl}\mathbf{\red{x = - 40 \div 2}}\end{array}}}}}\end{gathered}$

↬ Divida os números.

$\begin{gathered}\qquad\LARGE\red{\boxed{\red{\boxed{\begin{array}{rcl}\mathbf{\red{x = - 20}}\end{array}}}}}\end{gathered}$

↬ Cálculo completo:

${{\red{\boxed{\begin{array}{lr}\mathbf{2x = - 40} \\\mathbf{2x \div 2 = - 40 \div 2 } \\\mathbf{x = - 40 \div 2} \\ \mathbf{x = - 20}\end{array}}}}}$
