Question

Resuelve las ecuaciones y las inecuaciones

Answer 1

Respuesta:

Ecuaciones:

1.  x = 9

2. x = 206

3. x = 5

4. x = 1

5. x = 1

Inecuaciones:

1.     x > 1. 11

2.     x < 7.75

3.      5= x

4.      5= x

5.       x = 24.5

Explicación paso a paso:

Ecuaciones:

5x + 22 = 2x + 49

5x - 2x = 22 - 49

3x = 27

x = 27 /3

x = 9

x + 94 = 300

x = 300 - 94

x = 206

x + x + 1 = 11

2x = 11 - 1

x = 10 / 2

x = 5

4(x + 2) - 7(x - 2) = x + 6

4x + 8 - 7x - 14 = x + 6

4x - 7x - x = 6 - 8

2x = 2

x = 2 / 2

x = 1

4x - 9x + 2 = 7x - 5x - 9

4x - 7x + 5x + 9x = 2 + 9

11x = 11

x = 11 / 11

x = 1

Inecuaciones:

5(x - 3) > -9

5x - 15 > -9

10 x > -9

x > 10 / 9

x > 1. 11

x + (x + 1) + (x + 2) < 33

2x + 2 + 2x < 33

2x + 2x < 33 - 2

4x < 31

x < 31 /4

x < 7.75

7x - 6 < - 5x + 1

7x + 5x < 6 - 1

12x < 5

x = 5 / 12

x = 2.4

1 - 4x > 2 - x

1 - 2 > 4x + x

1 > 5x

5 / 1=x

5= x

2x + 7 mayor o igual 56

2x = 56 - 7

x = 49 / 2

x = 24.5
