13(x - 13) + 14(14x - 2) = 11(3x - 11) + 28 + (10х - 21) Решение: 13x - 169 + 196x - 28 = 33x - 121 + 28 + 10x - 21 209x - 197 = 43x - 114 209x - 43x = 197 - 114 166x = 83 x = 83/166 x = 0.5
13(x - 13) + 14(14x - 2) = 11(3x - 11) + 28 + (10х - 21) Решение: 13x - 169 + 196x - 28 = 33x - 121 + 28 + 10x - 21 209x - 197 = 43x - 114 209x - 43x = 197 - 114 166x = 83 x = 83/166 x = 0.5
