Answer 2

Olá!

Resolução⤵

$\mathbf{1.64 = x - \frac{646}{100} }$

$\mathbf{1.64 = \frac{164}{100} }$

$\mathbf{ \frac{164}{100} = x - \frac{646}{100} }$

$\mathbf{x = \frac{164}{100} + \frac{646}{100} }$

$\mathbf{ x = \frac{164 + 646}{100} }$

$\mathbf{x = \frac{810}{100} }$

$\boxed{ \mathbf{x = 8,1}}$

Resposta: x = 8,1
