Respuesta:
1. 2x = 6 x = 6/2 X = 3
2. 2x - 3 = 6 + x 2x -x = 6 + 3 x = 9
3, 5x - 3 = 66 + 2x 5x - 2x = 66 + 3 3x = 69 x = 69/3 x = 23
4. 2(2x - 3) = 6 + x 4x - 6 = 6 + x 4x - x = 6 + 6 3x = 12
x = 12/3 x = 4
5. 9x - 5 = 3(x - 2) + 13 9x - 5 = 3x - 6 + 13 9x - 3x = -6 + 13 + 5
6x = 12 x = 12/6 x = 2
6. NO SE ENTIENDE
7, 3(2X + 4) = X + 19 6X + 12 = X + 19 6X - X = 19 - 12 5X = 7 X = 7/5
8. 4(X - 10) = 6(2 - X) - 6X , 4X - 40 = 12 - 6X -6X , 4X +6X + 6X = 12 + 40
16X = 52 X = 52/16 X = 13/4
9. 2(x + 1) - 3(x -2) = x + 5 2x + 2 -3x + 6 = x + 5 2x - 3x - x = 5 -2 - 6
- 2x = - 3 x = - 3 / - 2 x = 3/2
10. x - 1 - x - 5 = x + 5 x - x - x = 5 + 1 + 5 , - x = 11 x = - 11
