5класс решите уравнение (104, 105) х+23=41; 36+y=74; 85+z=97; x-61=7; 46-y=24; 53-z=25; m ÷21 = 10; 192÷n=16; r ÷44=20;

x + 23 = 41

x = 41 - 23

x = 18

36 + y = 74

y = 74 - 36

y = 38

85 + z = 97

z = 97 - 85

z = 12

x - 61 = 7

x = 7 + 61

x = 68

46 - y = 24

y = 46 - 24

y = 22

53 - z = 25

z = 53 - 25

z = 28

m ÷ 21 = 10

m = 10 * 21

m = 210

192 ÷ n = 16

n = 192 ÷ 16

n = 12

r ÷ 44 = 20

r = 20 * 44

r = 880
