Answer 2

Question :

✏ 2.4x+1.35=3.75x+13.5

To Find :

✒ The value of x

$\huge\sf{\green{\underline{\underline{Required \: Answer}}}}$

$\: \\ \: \hspace{3em} : \implies \displaystyle \sf \: 2.4x + 1.35 = 3.75 + 13.5$

$\: \\ \hspace{3em} : \implies \displaystyle \sf \: 2.4x + 1.35 - 3.75 x - 13.5 = 0$

$\ \\ \hspace{3em} : \implies \displaystyle \sf \: 2.4x - 3.75x + 1.35 - 13.5 = 0$

$\ \\ \hspace{3em} : \implies \displaystyle \sf \: - 1.35x - 12.15 = 0$

$\: \\ \hspace{3em} : \implies \displaystyle \sf \: x = \frac{ - 12.15}{1.35}$

$\: \\ \hspace{3em} : \implies \displaystyle \bf{ \bullet \: \: { \underline{divide \: each \: term \: by \: 5}}}$

$\: \\ \hspace{3em} : \implies \displaystyle \sf \: x = \frac{ - 2.43}{0.27}$

$\: \\ \hspace{3em} : \implies \displaystyle \sf \: x = \frac{ - 0.81}{0.09}$

$\: \\ \hspace{3em} : \implies \displaystyle \boxed{ \underline{ \bf{the \: answer \: will \: be \: 9}}}$
