Question

Решите уравнения: (94,2-а)-1,26=3,254; 40,3-(63,4-а)=36,62

Answer 1

 (94,2-а)-1,26=3,254
94,2-а=3,254+1,26
94,2-а=4,514
а=94,2-4,514
а=89,686
проверка
94,2-89,686-1,26=3,254
4,514-1,26=3,254
3,254=3,254

40,3-(63,4-а)=36,62
40,3-63,4+а=36,62
-23,1+а=36,62
а=36,62+23,1
а=59,72
проверка
40,3-(63,4-59,72)=36,62
40,3-3,68=36,62
36,62=36,62
