Question

x-25=60, 73-x=40, 52+y=91 сделать уравнение

Answer 1

x-25=60
x=60+25
x=85

73-x=40
x=73-40
x=33

52+y=91 
y=91-52
y=39

Answer 2

1) x – 25 = 60
x = 60 + 25
x = 85
Проверка: 85 – 25 = 60
60 = 60

2) 73 – x = 40
x = 73 – 40
x = 33
Проверка: 73 – 33 = 40
40 = 40

3) 52 + у = 91
у = 91 – 52
у = 39
Проверка: 52 + 39 = 91
91 = 91
