124. Найдите корень уравнения: 1) 14x + 5x = 608; 2) 53x - 26x = 1 863; 3) x + 21x = 1 144; 4) 19x - x - 14 = 256; 5) 6y + 11y + 15 = 321; 6) 17x - 8x - 52 = 2 711.

1) 14x + 5x = 608 19x = 608 x = 608 / 19 **x = 32** 2) 53x - 26x = 1 863 27x = 1 863 x = 1 863 / 27 **x = 69** 3) x + 21x = 1 144 22x = 1 144 x = 1 144 / 22 **x = 52** 4) 19x - x - 14 = 256 18x - 14 = 256 18x = 256 + 14 18x = 270 x = 270 / 18 **x = 15** 5) 6y + 11y + 15 = 321 17y + 15 = 321 17y = 321 - 15 17y = 306 y = 306 / 17 **y = 18** 6) 17x - 8x - 52 = 2 711 9x - 52 = 2 711 9x = 2 711 + 52 9x = 2 763 x = 2 763 / 9 **x = 307**
