 =  > 3 (x-2) + 2(x-3) = 5(x - 1) - 7(x - 4)

 =  > 3x +3× (-2) + 2(x − 3) = 5(x - 1)- 7 (x-4)

 =  > 3x + 3× (-2) + 2x + 2 × (-3) = 5 (x- 1) - 7 (x-4)

 =  >  \: 3x + 3 × (-2) + 2x + 2 × (-3) =5x - 5 - 7 (x-4)

 =  > 3x + 3x (-2) + 2x + 2 × (-3) = 5x- 5- 7x - 7× (-4)

 =  > 3x −6+2x+ 2 × (-3) = 5x – 5 – 7x- 7 \times  (-4)

 =  > 3x −6+2x - 6 = 5x -5-7x - 7  \times ( - 4)

 =  > 5x-12=5x - 5 - 7x - 7 × (-4)

 =  > 5x-12 = 5x -5-7x +28

 =  > 5x - 12 + 2x = 23

 =  > 5x - 12  = - 2x - 5 + 28

 =  > 5x - 12 = -2x + 23

 =  > 5x - 6-6= 5x -5-7x-7x (-4)

 =  > 5x + 2x = 23 + 12

 =  > 7x = 23 + 12

 =  > 7x = 35

 =  > x =  \frac{35}{7}
