0.2(6x - 5) - 4(0.2x - 2) = 0.2 * 6x - 0.2 * 5 - (4 * 0.2x - 4 * 2) = 1.2x - 1 - 0.8x + 8 = 1.2x - 0.8x - 1 + 8 = x(1.2 - 0.8) + 7 = 0.4x + 7.
ответ: 0.4x + 7.
0.2(6x - 5) - 4(0.2x - 2) = 0.2 * 6x - 0.2 * 5 - (4 * 0.2x - 4 * 2) = 1.2x - 1 - 0.8x + 8 = 1.2x - 0.8x - 1 + 8 = x(1.2 - 0.8) + 7 = 0.4x + 7.
