Решите уравнения; 1. х+4 4\19=6 2\19 2. 25-х=8 3\14 3. 32-х=9 18\35

1. х + 4 целых 4 / 19 = 6 целых 2 / 19 х + ( 4 * 19 + 4 ) / 19 = ( 6 * 19 + 2 ) / 19 х + (76 + 4 ) / 19 = ( 72 + 2 ) / 19 х + 80 / 19 = 74 / 19 х = 74 / 19 - 80 / 19 х= ( 74 - 80 ) / 19 х = - 6 / 19 2. 25 - х = 8 целых 3 / 14 25 - х = ( 8 * 14 + 3 ) / 14 25 - х = ( 112 + 3 ) / 14 25 - х = 115 / 14 х = 115 / 14 - 25 х = ( 115 - 14 * 25 ) / 14 х = ( 115 - 350 ) / 14 х = 235 / 14 3. 32 - х = 9 целых 18 / 3532 - х = ( 9 * 35 + 18 ) / 35 32 - х = ( 315 + 18 ) / 35 32 - х = 333 / 35 - х = 333 / 35 - 32 х = 32 - 333 / 35 х = 787 / 35
