Question

1. 2x + 5 = 1 2. 3x = 21


3. 3x + 5 = 4x - 7 4. 3(x - 5) = 2(x + 2)


5. x = 27 6. 3 x = 6
9 5

7. x + 3 = x - 1 8. x + 9 = 2
2 3 5

Answer 1

Respuesta:

Explicación paso a paso:

1.  2x + 5 = 1

2x = 1-5

2x = -4

x = -4/2 =  -2

2. 3x = 21

x =21/3 = 7

3. 3x+5 = 4x - 7

3x - 4x = -7 - 5

- x = -12

x = 12

4. 3(x+5) = 2(x + 2)

3x + 15 = 2x + 4

3x - 2x = 4 - 15

x = - 11

5. x/9
