Question

Podrian ayudar con estas ecuaciones:

4(x-6)+5=13

6(3x+5)=5(8x+6)

-(x+8)=2(4x+5)

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

3(x+3)+2(2x-4)=12(2x-7)

21(x+1)-14(x-1)=12x

2x-8 - 22-x = 2
10 3

4x-14 = -6+ 6x+10
5 4

Answer 1

4(x-6)+5=13
4x - 24 + 5 = 13
4x - 19 = 13
4x = 13 + 19
4x = 32
x = 32/4
x = 8



6(3x+5)=5(8x+6)
18x + 30 = 40x + 30
18x - 40x = 30 - 30
- 22x = 0
x = 0/-22
x = 0



-(x+8)=2(4x+5)
- x - 8 = 8x + 10
- x - 8x = 10 + 8
- 9x = 18
x = 18/-9
x = - 2



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


3(x+3)+2(2x-4)=12(2x-7)
3x + 9 + 4x - 8 = 24x - 84
7x + 1 = 24x - 84
7x - 24x = - 84 - 1
- 17x = - 85
x = - 85/-17
x = 5


21(x+1)-14(x-1)=12x
21x + 21 - 14x + 14 = 12x
7x + 35 = 12x
7x - 12x = - 35
- 5x = - 35
x = - 35/-5
x = 7


NOTA. Las dos últimas no se entiende bien.
