Answer 2

Resposta:

$x = \frac{\sqrt[2]{7}}{3,5}$

Explicação passo a passo:

$\sqrt{7}x - 3 - 1 = x\\2\sqrt{7} -3-1 = 0\\2\sqrt{7} x = 4\\x = \frac{4}{2\sqrt{7} } .\frac{\sqrt{7} }{\sqrt{7} } \\x = \frac{4\sqrt{7} }{2.7} \\\\\\x =\frac{4\sqrt{7} }{14} } : \frac{4}{4} \\x = \frac{4\sqrt{7} }{3,5}$
