Question

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

2. 4x - (5 - 7x) - 6 = 11

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

4. 4 + 5x - (3 - 3x) = 6x - 7

5. 8 - 5x + 3(2 + x) = -(x + 6)

6. 9 - 3x + 2(3 - x) = -5(x + 4) - x

7. 5 - (3y - 6y - 8) - 7y = 2y + 16 - 9

8. 3(y - 4) = (3y - 5 - 4y) - (2 - 5y + 10)

9. 2m - (3 - 9m + 8) = 35 - (3m - 62 + 4m)

10. 8 - (7m - 4) - 36 = -5m - [4m - (8 - 2m)]

11. 3(x + 1) - 5(x + 5) = 4(1 - 2x) - 2(x - 3)

12. 5z - 7(z - 1) = -{2(z - 3) + z}

13. 3(x + 6) + 3 = 3 + 5(x - 4)

14. 11 + [3(x + 2) + 4] = [6(-2x - 2) + 1] - 13

15. 4 + 12(2x + 1) = 2 + 3(-2x + 8)

son ecuaciones faciles, por favor ayudenme

Respuesta:

1. 3x + (5 - 2x) + 4 = 6   =>   3x + 5 - 2x + 4 = 6  =>  x+9=6  =>  x=-3
2. 4x - (5 - 7x) - 6 = 11  =>  4x - 5 + 7x - 6 = 11  =>  11x-11=11  =>  11x=22  =>  x=2
3. -3x + 2 - (x + 3) = -5x + 4  =>  -3x + 2 - x - 3 = -5x + 4  =>  -4x-1=-5x+4  =>  x=5
4. 4 + 5x - (3 - 3x) = 6x - 7  =>  4 + 5x - 3 + 3x = 6x - 7  =>1+8x=6x-7  =>  2x=-8  =>  x=-4
5. 8 - 5x + 3(2 + x) = -(x + 6)  =>  8-5x+6+3x=-x-6  =>  14-2x=-x-6  =>  -x=-20  =>  x=20
6. 9 - 3x + 2(3 - x) = -5(x + 4) - x  =>  15-5x=4x+20  =>  -9x=5  =>  x=-5/9
7. 5 - (3y - 6y - 8) - 7y = 2y + 16 - 9  =>  5+3y+8-7y=2y+7  =>  -4y-2y=7-13  =>  y=1
