Hey Here is your answer

x - (2x - \frac{3x - 4}{7}) = \frac{4x - 27}{3} - 3 \\  \\ x - 2x +  \frac{3x - 4}{7}  = \frac{4x - 27}{3} - 3  \\  \\ x - 2x +  \frac{3x - 4}{7} -  \frac{4x - 27}{3} =  - 3  \\  \\  \frac{(21 \times x) - (21 \times 2x) + 3(3x - 4) - 7(4x - 27)}{21}  =  - 3 \\  \\  \frac{21x - 42x + 9x - 12 - 28x + 189}{21}  =  - 3 \\  \\  \frac{ - 40x + 177}{21}  =  - 3 \\  \\- 40x + 177 =  - 3 \times 21 \\  \\  - 40x =  - 63 - 177 \\  \\  - 40x =  - 240 \\  \\ 40x = 240 \\  \\ x =  \frac{240}{40}   \\  \\ \bf \:  x = 6 \:  \:  \: answer

hope this helps you
