 \:  \:  \large \green{  \bold{ \underline{step \: by \: step \: explaination}}}

 \:  \implies \displaystyle \sf{ \frac{5x - 8}{5x + 7}  -  \frac{3x + 3}{3x + 5}}

 \:   \\ \implies \displaystyle \sf{ \frac{5x(3x + 5) - 8(3x + 5) - (3x(5x + 7) + 3(5x + 7)}{5x(3x + 5) + 7(3x + 5)} }

 \:  \\  \implies \displaystyle \sf \:  \frac{15 {x}^{2}  + 15x - 24x - 40 - (15 {x}^{2} + 21x + 15x + 21) }{15 {x}^{2}  + 25x + 21x + 35}

 \:   \\ \:  \implies \displaystyle \sf{ \frac{15 {x}^{2} - 9x - 40 - ( 15{x}^{2}  + 36x + 21) }{15 {x}^{2}  + 46x + 35} }

 \:  \\  \implies \displaystyle \sf \:  \frac{15 {x}^{2}  -  9x - 40 -15  {x}^{2} - 36x - 21 }{15 {x}^{2} + 46 + 35 }

 \:  \implies \displaystyle \sf \:   \frac{ - 45x - 61}{15 {x}^{2}  + 46 + 35}

 \:  \:  \implies \displaystyle \sf \:  \frac{ - 45x - 61}{15 {x}^{2}  + 46 + 35}  = 0

 \:  \:  \implies \displaystyle \sf \:  - 45x = 61

 \:  \implies \displaystyle \sf \: x =  \frac{ - 61}{45}

 \:  \:  \bigstar \boxed{ \underline{ \bf{x =  \frac{ - 61}{45} \:   is \: the \: answer \: of \: this \: question}}}
