Question

me ayudan lo necesito con las siguientes ecuaciones debEN sacar el valor de X
1. x + 7 = 22
x = -15
x = 15
x = 29
x = -29

2. x - 20 = 40
x = 21
x = -20
x = 60
x = 20

3. 6x = 42
x = 36
x = 48
x = 7
x = -7

4. x/3 = 9
x = 3
x = 27
x = 6
x = -6

5. x / 5 - 4 = 16
x = 10
x = 100
x = -20
x = -10

6. 5x - 5 = 2x + 16
x = 5
x = 7
x =-7
x = -5

7. 5x + 10 = 2x + 40
x = 10
x = -20
x = 5
x = -10

8. 4x - 3 = 3x + 2
x = -5
x = 10
x = 5
x = 15

9. 6x - 6 = 5x + 5
x = 10
x = -11
x = 11
x = 5

10. 7x -5 = 2x + 15
x = 5
x = -5
x = 4
x = -4

Answer 1

Respuesta:

1. x = 15

2. x = 60

3. x = 7

4. x = 27

5. x = 4

6. x = 7

7. x = 10

8. x = 5

9. x = 11

10. x = 4

Explicación paso a paso:

1) x + 7 = 22

x = 22 - 7

x = 15

2) x - 20 = 40

x = 40 + 20

x = 60

3) 6x = 42

x = 42 ÷ 6

x = 7

4) x / 3 = 9

x = 9 . 3

x = 27

5) x / 5 - 4 = 16

x / 5 = 16 + 4

x / 5 = 20

x = 20 ÷ 5

x = 4

6) 5x - 5 = 2x + 16

5x - 2x = 16 + 5

3x = 21

x = 21 ÷ 3

x = 7

7) 5x + 10 = 2x + 40

5x - 2x = 40 - 10

3x = 30

x = 30 ÷ 3

x = 10

8) 4x - 3 = 3x + 2

4x - 3x = 2 + 3

x = 5

9) 6x - 6 = 5x + 5

6x - 5x = 5 + 6

x = 11

10) 7x - 5 = 2x + 15

7x - 2x = 15 + 5

5x = 20

x = 20 ÷ 5

x = 4

Answer 2

Respuesta:

1. x = 15

2. x = 60

3. x = 7

4. x = 27

5. x = 4

6. x = 7

7. x = 10

8. x = 5

9. x = 11

10. x = 4

Explicación paso a paso:

1) x + 7 = 22

x = 22 - 7

x = 15

2) x - 20 = 40

x = 40 + 20

x = 60

3) 6x = 42

x = 42 ÷ 6

x = 7

4) x / 3 = 9

x = 9 . 3

x = 27

5) x / 5 - 4 = 16

x / 5 = 16 + 4

x / 5 = 20

x = 20 ÷ 5

x = 4

1.

6) 5x - 5 = 2x + 16

5x - 2x = 16 + 5

3x = 21

x = 21 ÷ 3

x = 7

7) 5x + 10 = 2x + 40

5x - 2x = 40 - 10

3x = 30

x = 30 ÷ 3

x = 10

8) 4x - 3 = 3x + 2

4x - 3x = 2 + 3

x = 5

9) 6x - 6 = 5x + 5

6x - 5x = 5 + 6

x = 11

10) 7x - 5 = 2x + 15

7x - 2x = 15 + 5

5x = 20

x = 20 ÷ 5

x = 4
