Question

2/3=4/5*99-x solve this equation

Answer 1

$\textbf{\huge\underline{\underline\red{solution} : - }}$

$\tt\red\dashrightarrow{\huge\purple{ \frac{2}{3} = \frac{4}{5} \times 99 - x }}$

$\sf\red{i.e.}$

$\tt\red\dashrightarrow{\huge\purple{ \frac{4}{5} \times 99 - x = \frac{2}{3} }}$

$\tt\red\dashrightarrow{\huge\purple{99 - x = \frac{2}{3} \times \frac{5}{4} }}$

$\tt\red\dashrightarrow{\huge\purple{9 - x = \frac{10}{12} }}$

$\tt\red\dashrightarrow{\huge\purple{ 9 - x = \frac{5}{6} }}$

$\tt\red\dashrightarrow{\huge\purple{ - x = \frac{5}{6} - 9}}$

$\tt\red\dashrightarrow{\huge\purple{ - x = \frac{5}{6} - \frac{9 \times 6}{6} }}$

$\tt\red\dashrightarrow{\huge\purple{ - x = \frac{5}{6} - \frac{54}{6} }}$

$\tt\red\dashrightarrow{\huge\purple{ - x = \frac{5 - 54}{6} }}$

$\tt\red\dashrightarrow{\huge\purple{ \cancel{-} x = \cancel{-} \frac{49}{6} }}$

$\tt\red\dashrightarrow{\huge\purple{ x = \frac{49}{6} }}$
