Answer:

 \frac{(4x + 7)}{(2x + 6}  =  \frac{(6x + 5)}{(3x + 5)}  \\  =  \frac{(4x + 7)}{(2x + 6)}  -  \frac{(6x + 5)}{(3x + 5)}   = 0\\  tak e \: a \:lcm \\  =  \frac{(4x + 7)(3x + 5) - (6x + 5)(2x + 6)}{(2x + 6)(3x + 5)} = 0   \\  =  \frac{ {12x}^{2} + 20x + 21x + 35 - ( \frac{}{}  {12x}^{2}  + 36x + 10x + 30) }{ {6x }^{2} + 10x + 18x + 30 }  = 0 \\  =  \frac{ {12x}^{2}  + 41x + 35 -  {12x}^{2} - 46x - 30 }{ {6x}^{2}  + 28x + 30}  = 0 \\  =  \frac{5 - 5x}{ {6x}^{2}  + 28x + 30}  = 0 \\  take \: a \: denominator \: to \: rhs \: its \: become \: zero \\  = 5 - 5x = 0 \\ 5 = 5x \\ x = 1

i hope u will find ur answer
