     \mathfrak \blue{ \underline{ \underline{here \: is \: your \: answer : }}} \\ 7tan \theta = 4 \\ tan \theta =  \frac{sin \theta}{cos \theta}  =  \frac{4}{7}  \\ so... \\  \frac{7sin \theta - 3cos \theta}{7sin \theta  + 3cos \theta}  \\  \frac{7(4)- 3(7)}{7(4)  + 3(7)}  \\  \frac{28 - 21}{28 + 21}  \\  \frac{7}{49}  \\  \frac{1}{7}

    Hope my answer will help you…
