Question

Me podrían ayudar con este problema, por favor: 22x-20=14-4(2x-2)​

Answer 1

Respuesta:

x= 7/5

Explicación paso a paso:

$22x-20=14-4(2x-2)\\\\22x-20=14-8x+8\\\\22x+8x= 14+8+20\\\\30x= 42 \\\\x= \frac{42}{30} \\\\x= \frac{7}{5}$

Comprobación:

$22 (\frac{7}{5})-20= 14-4 (2 (\frac{7}{5} )-2)\\\\\frac{154}{5}-20= 14-4 (\frac{14}{5}-2)\\\\ \frac{154}{5}-20= 14-\frac{56}{5}+8\\\\\frac{154-(5)(20)}{5} = \frac{(5)(14)-56+(5)(8)}{5} \\\\\frac{154-100}{5} = \frac{70-56+40}{5} \\\\\frac{54}{5}= \frac{54}{5}$

Espero sea de ayuda!
