Решите уровнениия*= это умножить 31*(8x-14+x)=682 32*(15x-6x-2)=800 1431:(363-8x)=53 3168:(1032-19x)=72

31 * (8х - 14 + х) = 682 8х - 14 +х = 682 : 31 8х - 14 + х = 22 8х + х = 22 + 14 9х = 36 х = 36 : 9  х = 4 32 * (15х - 6х -2) = 800 15х - 6х - 2 = 800 : 32 15 х - 6х - 2 = 25 15х - 6х = 25 + 2 9х = 27 х = 27 : 9 х = 3 1431 : (363 - 8х) = 53 363 - 8х = 1431 : 53 363 - 8х = 27 8х = 363 - 27 8х = 336 х = 336 : 8 х = 42 3168 : (1032 - 19х) = 72 1032 - 19х = 3168 : 72 1032 - 19х = 44 19х = 1032 - 44 19х = 988 х = 988 : 19 х = 52
