a) (5x-1)-(2-8x) = 5x - 1 - 2 + 8x = 13x - 3
При x = 0.75: 13 * 0.75 - 3 = 9.75 - 3 = 6.75
Ответ: 6.75
b) (6-2x) + (15 - 3x) = 6 - 2x + 15 - 3x = 21 - 5x
При x = -0.2: 21 - 5*(-0.2) = 21 + 1 = 22
Ответ: 22
c) 12 + 7x - (1-3x) = 12 + 7x - 1 + 3x = 10x + 11
При x = -1.7: 10*(-1.7) + 11 = -17 + 11 = -6
Ответ: -6
d) 37 - (x - 16) + (11x-53) = 37 - x + 16 + 11x - 53 = 12x
При x = -0.03: 12 * (-0.03) = -0.36
