Question

1. Ejercicios
2x – 1= 5x + 8
3 + 3x – 1 = x + 2 + 2x
2(1 + 2x) = 10
• 2(3x - 2) = 2
-2(3x - 2) = -2
5 - 2(1 - x) = 2x - 3
x-3= 3 - x
3x + 1 = 3 - (2 - 2x)
2(2 + x)-(6-7x)=13x-(1+4x)
5(x-1)-(1-x)=2(x-1)-4(1-x)​

Answer 1

Respuesta:

1. 2x - 1 = 5x + 8

-9 = 3x = -3

2. 3 + 3x -1 = x + 2 + 2x

2 + 3x = 3x + 2 = 0

3. 2(1 + 2x) = 10

2 + 4x = 10

4x = 8 = 2

4. 2(3x - 2) = 2

6x -4 = 2

6x = 6 = 1

5. -2(3x - 2) = -2

-6x +4 = -2

-6x = -6 = 1

6. 5 - 2(1 - x) = 2x - 3

5 - 2 +2x = 2x - 3

3 + 2x = 2x - 3

x = 6

7. x-3= 3 - x

2x = 6 = 3

8. 3x + 1 = 3 - (2 - 2x)

3x + 1 = 3 - 2 + 2x

3x + 1 = 1 + 2x

x = 0

9. 2(2 + x)-(6-7x)=13x-(1+4x)

4 + 2x - 6 + 7x = 13x - 1 - 4x

9x - 6 = 9x - 1

x= 5

10. 5(x-1)-(1-x)=2(x-1)-4(1-x)

5x - 5 - 1 + x = 2x - 2 - 4 + 4 x

6x - 6 = 6x - 6

x = 0
