Explicación paso a paso:

2(x + 1) - 3(x - 2) = x + 6 \\ 2x + 2 - 3x + 6 = x + 6 \\  - x + 8 = x + 6 \\  - 6 + 8 = x + x \\ 2 = 2x \\ x =  \frac{2}{2}  = 1 \\ x = 1

3 + 4(x - 2) = 7 \\ 3 + 4x - 8 = 7 \\ 4x = 7 + 8 - 3 \\ 4x = 15 - 3 \\ 4x = 12 \\ x =  \frac{12}{4}  =  3 \\ x = 3

 - 3(x - 1) - 2 = 10 \\  - 3x + 3 - 2 = 10 \\  - 3x = 10 + 2 - 3 \\  - 3x = 12 - 3 \\  - 3x = 9 \\ 3x =  - 9 \\ x =  \frac{ - 9}{3}  =  - 3 \\ x =  - 3

espero te sirva
