30+×=50 X+13=77 X-22=80 40-×=11

Answer 1

Ответ:

Пошаговое объяснение:

1)30+х=50

х=50-30

х=20

2)х+13=77

х=77-13

х=64

3)х-22=80

х=80+22

х=102

4)40-х=11

-х=11-40

-х=-29 |:(-1)

х=29

Answer 2

To solve these equations for the value of "x," follow these steps:

1. 30 + x = 50
2. x + 13 = 77
3. x - 22 = 80
4. 40 - x = 11

Let's solve them one by one:

1. 30 + x = 50 Subtract 30 from both sides to isolate "x": x = 50 - 30 x = 20

2. x + 13 = 77 Subtract 13 from both sides to isolate "x": x = 77 - 13 x = 64

3. x - 22 = 80 Add 22 to both sides to isolate "x": x = 80 + 22 x = 102

4. 40 - x = 11 Subtract 40 from both sides to isolate "x": -x = 11 - 40 -x = -29

Now, to find the value of "x," multiply both sides by -1 (to remove the negative sign): x = -(-29) x = 29

So, the solutions to the equations are: x = 20 x = 64 x = 102 x = 29
