Решите уравнения:
a) n+37=81;b)150-s=98;c)48+x+57=144;d)87+49-k=58;e)(58+x)-23=96;f)54-(x-19)=35
​

Answer 1

Ответ:

a) n+37=81

n= 81 - 37

n = 44

b)150-s=98

s= 150 - 98

s = 52

c)48+x+57=144

x = 144 - (48 + 57)

x = 144 - 105

x = 39

d)87+49-k=58

k = (87 + 49) - 58

k = 136 - 58

k = 78

e)(58+x)-23=96

58 + x = 96 - 23

58 + x = 73

x = 73 - 58

x = 15

f)54-(x-19)=35

x-19 = 54 - 35

x-19 = 19

x = 19 + 19

x = 38

Надеюсь помогла. Удачи!
