1)4x + 5 = 2x - 1 \\ 2x = - 6 \\ x = - 3
2)5(x + 2) - 3(x + 8) = 4(x - 2) \\ 5x + 10 - 3x - 24 = 4x - 8 \\ 2x - 14 = 4x - 8 \\ - 2x = 6 \\ - x = 3 \\ x = - 3
3)7(2x + 3) - 5 = 3(5x + 11) \\ 14x + 21 - 5 = 15x + 33 \\ - x + 16 = 33 \\ - x = 17 \\ x = - 17
4)(x - \sqrt{3} ) + ( \sqrt{3} + x) = x - 2 \\ x - \sqrt{3} + \sqrt{3} + x = x - 2 \\ 2x = x - 2 \\ x = - 2
