Question

1. x + 25 = 54
2. X - 25 = 90
3. 53 - X = 1
4. x 5 = 355
5.X-12 = 5
6. 280-X = 45​

Answer 1

Ответ:

1. x + 25 = 54

x = 54 -25

x = 29

2. x - 25 = 90

x = 90 + 25

x = 115

3. 53- x = 1

x = 53 - 1

x = 52

4. x5 = 355

x = 355 : 5

x = 71

5.x - 12 = 5

x = 12 + 5

x = 17

6.280 - x = 54

x = 280 - 45 = 235

Answer 2

1

x+25=54

x=54-25

x=29

2

x-25=90

x=25+90

x=115

3

53-x=1

x=53-1

x=52

4

x5=355

x=355:5

x=71

5

x-12=5

x=12+5

x=17

6

280-x=45

x=280-45

x=235
