5x + 796 = 1021
5x = 225
x = 45
856 + x/6 = 1224
x/6 = 368
x = 2208
x - 2095 = 304 * 80
x - 2095 = 24320
x = 26415
(x + 240) * 3 = 1260
3x = 1260 - 720
3x = 540
x = 180
x + (240 * 3) = 1260
x + 720 = 1260
x = 540
x + 240 = 1260 * 3
x = 3780 - 240
x = 3540
И еще надо найти уравнения с одинаковыми корнями:
х * 700 - 460 = 289000
700x = 289000 + 460
700x = 289460
x = 416.52
у * 700 = 288999 + 461
700y =
d * 700 = 288999 + 459
