Question

решите уравнение пожалуйста!!! x-18=29 x+15=25 64-a=52 17+b=28 x-23=57 48-x=20​

Answer 1

x - 18 = 29

x = 29 + 18

x = 47

x + 15 = 25

x = 25 - 15

x = 10

64 - a = 52

a = 64 - 52

a = 12

17 + b = 28

b = 28 - 17

b = 11

x - 23 = 57

x = 57 + 23

x = 80

48 - x = 20​

x = 48 - 20

x = 28
