Question

Помогите 504 - X = 102376 + Y = 400X • 40= 120X : 5 = 68

Answer 1

504 - х =102

х=504-102

х=402

___________________________

376 + у =400

у=400-376

у= 24

______________________________

х*40 = 120

х= 120:40

х=3

_________________________________

х :5 =68

х = 68*5

х = 340

Answer 2

1) х=504-102=402
2) у=400-376=24
3) х=120:40=3
4) х=68*5=340
