Answer 1

Ответ:

Пожалуйста

Пошаговое объяснение:

1) х-20+15+15-50=-12

х-70+30+12=0

х=-28

2) X+15-10-39+8=20

х-26=20

х=46

3) X-200+450-130+150=7250

х+270=7250

х=6980

4)  X-8+5-3+7+10=27

х+11=27

х=16

Answer 2

Let's solve each of the equations step by step:

1. X - 20 + 15 + 15 - 50 = -12

Combine the numbers on the left side: X - 40 = -12

Add 40 to both sides to isolate X: X - 40 + 40 = -12 + 40 X = 28

Therefore, X = 28.

2. X + 15 - 10 - 39 + 8 = 20

Combine the numbers on the left side: X - 26 = 20

Add 26 to both sides to isolate X: X - 26 + 26 = 20 + 26 X = 46

Therefore, X = 46.

3. X - 200 + 450 - 130 + 150 = 7250

Combine the numbers on the left side: X + 270 = 7250

Subtract 270 from both sides to isolate X: X + 270 - 270 = 7250 - 270 X = 6980

Therefore, X = 6980.

4. X - 8 + 5 - 3 + 7 + 10 = 27

Combine the numbers on the left side: X + 11 = 27

Subtract 11 from both sides to isolate X: X + 11 - 11 = 27 - 11 X = 16

Therefore, X = 16.

To summarize the solutions:

1. X = 28
2. X = 46
3. X = 6980
4. X = 16
