Решение уравнений

1. a) 6x + 2x + 97 = 1561
   • 8x + 97 = 1561
   • 8x = 1561 - 97
   • 8x = 1464
   • x = 1464 / 8
   • x = 183
2. б) 344t - 137t - 2861 = 10 387
   • 207t - 2861 = 10 387
   • 207t = 10 387 + 2861
   • 207t = 13 248
   • t = 13 248 / 207
   • t = 64
3. в) 3y + 6y + 78 = 1617
   • 9y + 78 = 1617
   • 9y = 1617 - 78
   • 9y = 1539
   • y = 1539 / 9
   • y = 171
4. г) 345m - 236m - 1972 = 63 755
   • 109m - 1972 = 63 755
   • 109m = 63 755 + 1972
   • 109m = 65 727
   • m = 65 727 / 109
   • m = 603
