Question

1) 4x = 2x - 12

2) 8x - 24 = 5x

3) 7x +12 = 4x - 17

4) 3x- 25 = x - 5

5) 5x + 13 = 10x + 12

6) 12x - 10 = - 11 + 9x

7) 36 - 6x = 34 - 4x

8) 10x - 25 = 65 x - 36

9) 11x - 1 + 5x = 65 x - 36

10) 4x - 13 - 5x = - 12x + 9 + 8x

Answer 1

1) 4x = 2x - 12
4x - 2x = - 12
2x = - 12
x = - 12/2
x = - 6



2) 8x - 24 = 5x
8x - 5x = 24
3x = 24
x = 24/3
x = 8



3) 7x +12 = 4x - 17
7x - 4x = - 17 - 12
3x = - 29
x = - 29/3



4) 3x- 25 = x - 5
3x - x = - 5 + 25
2x = 20
x = 20/2
x = 10


5) 5x + 13 = 10x + 12
5x - 10x = 12 - 13
- 5x = - 1
x = - 1/-5
x = 1/5



6) 12x - 10 = - 11 + 9x
12x - 9x = - 11 + 10
3x = - 1
x = - 1/3


7) 36 - 6x = 34 - 4x
- 6x + 4x = 34 - 36
- 2x = - 2
x = - 2/-2
x = 1



8) 10x - 25 = 65x - 36 
10x - 65x = - 36 + 25
- 55x = - 11
x = - 11/-55
x = 1/5



9) 11x - 1 + 5x = 65 x - 36
11x + 5x - 1 = 65x - 36
16x - 1 = 65x - 36
16x - 65x = - 36 + 1
- 49x = - 35
x = - 35/-49
x = 35/49
x = 5/7


10) 4x - 13 - 5x = - 12x + 9 + 8x
4x - 5x - 13 = - 12x + 8x + 9
- x - 13 = - 4x + 9
- x + 4x = 9 + 13
3x = 22
x = 22/3


Listo!!!
