Question

$\frac{3x}{10} = \frac{9}{25} - \frac{21}{5}$
​

Answer 1

$\: \: \: \: \huge \tt\frac{3x}{10} = \frac{9}{25} - \frac{21}{5} \\ \\ \sf\to 3x \: \: = 10 \bigg( \frac{9 - 105}{25} \bigg) \\ \\ \sf \to x = \frac{10}{3}\bigg( \frac{ -96 }{25} \bigg) \\ \\ \sf \to x = \frac{10}{3} \times\bigg( \frac{3 \times ( - 32)}{5 \times 5} \bigg) \\ \\ \sf \to x = \frac{ \cancel5 \times 2}{ \cancel3} \times \frac{ \cancel3 \times ( - 32)}{5 \times \cancel5} \\ \\ \sf \to x = \frac{ \red{- 64}}{ \red5}$

Hence,

• The value of x is (-64)/5
