Answer 1

Resposta:

olá

Explicação passo-a-passo:

3x + 1 = 10

3x = 10 - 1

3x = 9

x = 9 / 3

x = 3<----------------resposta

Answer 2

$\rightarrowtail\mathbb{EQUAC_{\!\!\!,}\tilde{A}O}$

⚡ Para encontrarmos o valor de x, vamos mover a constante.

⚡Depois, subtrair e dividir, simples!

$\rightarrowtail\mathbb{EXPLICAC_{\!\!\!,}\tilde{A}O}$

$\boxed{\begin{array}{lr}\mathtt{3x + 1 = 10}\end{array}}$

• Movimente a constante para o lado direito, e adicione seu oposto!

$\boxed{\begin{array}{lr}\mathtt{3x + 1 - 1 = 10 - 1}\end{array}}$

• Somando dois opostos, iremos encontrar o valor de 0. Logo, são inúteis na equação!

$\boxed{\begin{array}{lr}\mathtt{3x = 10 - 1}\end{array}}$

• Subtraia!

$\boxed{\begin{array}{lr}\mathtt{3x = 9}\end{array}}$

• Divida os membros por 3.

$\boxed{\begin{array}{lr}\mathtt{3x \div 3 = 9 \div 3}\end{array}}$

• Divida...

$\boxed{\begin{array}{lr}\mathtt{x = 9 \div 3}\end{array}}$

• E divida...

$\boxed{\begin{array}{lr}\mathtt{ x= 3}\end{array}}$

$\rightarrowtail\mathbb{CONTA \: ARMADA}$

$\boxed{\begin{array}{lr}\mathtt{3x + 1 = 10} \\\mathtt{3x = 10 - 1} \\ \mathtt{3x = 9} \\\mathtt{x = 3} \end{array}}$
