Question

Решите уравнения: 406-(451-m)=340, 825-(n+176)=49

Answer 1

406-(451-m)=340,
406-451+m=340
m - 45 = 340
m = 340 + 45
m =  385


825-(n+176)=49
825- n -176=49
- n + 649 = 49
- n  = 49 -  649
- n  = -  600
n  = 600

Answer 2

406-(451-m)=340
451-m=406-340
451-m=66
m=451-66
m=385`

825-(n+176)=49
n+176=825-49
n+176=776
n=776-176
n=600
