Hey MATE ❤️

Here is your answer ⤵️

Solution :

\longrightarrow \sf \frac{7x + 4 }{x + 2} = - \frac{4}{3} \\

\longrightarrow \sf 3(7x + 4) = -4 (x + 2) \\

\longrightarrow \sf 21x + 12 = - 4 x - 8 \\

\longrightarrow \sf 21x + 4x = -12 - 8 \\

\longrightarrow \sf 25x = - 20 \\

\longrightarrow \sf x = - \frac{20}{25 } \\

\longrightarrow \sf x = - \frac{\cancel{20}^{\: \: \cancel{5} × 4 }}{\cancel{25}_{\: \: 5 × \cancel{5} }} \\

\longrightarrow \underline{\boxed{ \sf x = - \frac{4}{5}}} \\

HENCE, Option (C) is RIGHT ✔️

I HOPE it helps you ❤️✔️
