Question

¿Me podrían colaborar con estas ecuaciones? Muchas gracias.

2 - × = × - 8
2× - 1 = 5× + 8
3 + 3× - 1 = × + 2 + 2×
2( 1 + 2×) = 10
2( 3× - 2) = 2
-2( 3× - 2 ) = -2
2× - 3 = 6 + ×
2(2× - 3) = 6 + ×
8× + 4 = 4×
2 - 5× = 17
1 - 9× = -2

Answer 1

1) 2 - x = x - 8
2=8
No existe solución

2) 2x - 1 = 5x + 8
2x - 5x = 8 + 1
-3x = 9
x = 9/-3
x= -3

3) 3 + 3x - 1 = x + 2 + 2x
2 + 3x = 2 + 3x
2 - 2 = 3x - 3x
No existe solución

4) 2 (1 + 2x) = 10
2 + 4x = 10
4x = 10 - 2
4x = 8
x = 8/4
x = 2

5) 2 ( 3x - 2) = 2
6x - 4 = 2
6x = 2 + 4
6x = 6
x = 6/6
x = 1

6) -2 (3x - 2) = -2
-6x + 4 = -2
-6x = -2 - 4
-6x = -6
x = -6/-6
x = 1

7) 2x - 3 = 6 + x
2x - x = 6 + 3
x = 9

8) 2 (2x - 3) = 6 + x
4x - 6 = 6 + x
4x - x = 6 + 6
3x = 12
x = 12/3
x = 4

9) 8x + 4 = 4x
8x - 4x = -4
4x = -4x
x = 4/-4
x = -1

10) 2 - 5x = 17
-5x = 17 - 2
-5x = 15
x = 15/-5
x = -3

11) 1 - 9x = -2
-9x = -2 + 1
-9x = -1
x = -1/-9
