Explicação passo-a-passo:

Answer 2

$\LARGE\displaystyle{}72 - 10x = 21x \\\LARGE\displaystyle{} - 10x = 21x + 72 \\ \LARGE\displaystyle{} - 10x - 21x = 72 \\ \LARGE\displaystyle{} - 31x = - 72 \\ \LARGE\displaystyle{} - 31x \div \left( - 31\right) = - 72 \div \left( - 31\right) \\ \LARGE\displaystyle{}x = - 72 \div \left( - 31\right) \\ \LARGE\displaystyle{}x = 72 \div 31 \\ \\ \LARGE\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{ -21x72 }}}\end{gathered} }$

$\LARGE\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{{ \red{Bons}} \blue{\:Estudos}}}}\end{gathered} }$
