Помогите пожалуйста номер 363 , 364, 365, 366,

363

1) x + 50*50 = 45*100

x + 2500 = 4500

x = 2500 - 4500

x = -2000

2) x - 9*100 = 50*40

x - 900 = 2000

x = 900 - 2000

x = -2900

3) 8*1000 - x = 30*60

8000 - x = 1800

x = 8000 - 1800

x = 6200

4) 100*37 + x = 80*90

3700 + x = 7200

x = 3700 + 7200

x = 9900

364

1) x - 1683 = 230

x = -1683-230

x = -1913

2) 2832 + x = 3800

x = 2832 + 3800

x = 6632

3) 4823 + x = 5400

x = 4823 + 5400

x = 10223

4) x - 410 = 289

x = -410-289

x = -699

365

1) (x-213):(43+17)=100

x-213:50-100=0

x = -4,26-100

x = -104,26

2) (2500+x):(83+17)=43

2500+x:100-43=0

x = 25 - 43

x = -18

3) (x+17):(25+975)=57

x+17:1000-57=0

x = 59 - 57

x = 2

4) (x+101):(93+28)=100

x+101:121-100=0

x = 0,83 - 100

x = -99,17

366 при a = 175, b = 83, c = 100. Подставляем:

1) ac+bc = 175+100+83+100 = 458

2) ac-bc = 175+100-83+100 = 275-183 = 92
