Answer 2

Step-by-step explanation:

$\bf \huge \: \: Question \: \:$

$\tt\: \to \frac{2}{5} - 8 \times \frac{2}{5} -4=\frac{2}{5} -4x$

_______________________________

$\bf \huge \: \: Solve \: \:$

$\tt\: \to \frac{2}{5} - 8 \times \frac{2}{5} -4=\frac{2}{5} -4x$

$\tt\: \to \frac{2-40}{5} \times\frac{2-20}{5} =\frac{2-20x}{5}\: \\ \:$

$\tt\: \to \frac{-38}{5} \frac{-18}{5} =\frac{-18x}{5}\: \:$

$\tt\: \to \frac{684}{25} =\frac{-18x}{5}\: \:$

On cross multiplication

$\tt\: \to-450X =3420</u></strong><strong><u>\: \: </u></strong><strong><u>\\</u></strong><strong><u>$

$\tt\: \to</u></strong><strong><u> </u></strong><strong><u>X</u></strong><strong><u> </u></strong><strong><u>=</u></strong><strong><u> </u></strong><strong><u>-</u></strong><strong><u> \frac{</u></strong><strong><u>3</u></strong><strong><u>4</u></strong><strong><u>2</u></strong><strong><u>0</u></strong><strong><u>}{</u></strong><strong><u>4</u></strong><strong><u>5</u></strong><strong><u>0</u></strong><strong><u>} </u></strong><strong><u>\:</u></strong><strong><u>\\</u></strong><strong><u>$

$\tt\: \to X</u></strong><strong><u> </u></strong><strong><u>=</u></strong><strong><u> </u></strong><strong><u> </u></strong><strong><u>- \frac{</u></strong><strong><u>1</u></strong><strong><u>1</u></strong><strong><u>4</u></strong><strong><u>}{</u></strong><strong><u>1</u></strong><strong><u>5</u></strong><strong><u>} \:</u></strong><strong><u>\\</u></strong><strong><u>$

$\tt\: \to X = - \frac{38}{5} \:$

$\tt\red{ \to X = -7.6}\:$
