_ 0,4 / x - 1 = 10/ 4,5​

Answer 1

Respuesta:

x = 18/145

Explicación paso a paso:

Resolver:

$\sf0.4 \div x - 1 = 10 \div 4.5$

$\sf0.4 \div x - 1 = 10 \div 4.5,x ≠ 0$

$\sf \frac{2}{5} \times \frac{1}{x} - 1 = 10 \div \frac{9}{2}$

$\sf \frac{2}{5x} - 1 = 10 \times \frac{2}{9}$

$\sf \frac{2}{5x} - 1 = \frac{20}{9}$

$\sf \frac{2}{5x} = \frac{20}{9} + 1$

$\sf \frac{2}{5x} = 145x$

$\sf145x = 18$

$\sf{x = \frac{18}{145},x ≠ 0 }$

$\boxed{ \sf{x = \frac{18}{145} }}$
