Question

Resuelve las siguientes ecuaciones:
-5(x+3)+2(x-1)= -14
6(-2x+5)= -18
2(4x+1)-3(2x+3)= 5
2(x-15) = 8x
6(3x+5) = 5(8x+6)

Answer 1

-5(x+3)+2(x-1)= -14
- 5x - 15 + 2x - 2 = - 14
- 5x + 2x - 15 - 2 = - 14
- 3x - 17 = - 14
- 3x = - 14 + 17
- 3x = 3
x = 3/-3
x = - 1

Respuesta.
x = - 1




6(-2x+5)= -18
- 12x + 30 = - 18
-12x = - 18 - 30
- 12x = - 48
x = - 48/-12
x = 4

Respuesta.
x = 4



2(4x+1)-3(2x+3)= 5
8x + 2 - 6x - 9 = 5
8x - 6x + 2 - 9 = 5
2x - 7 = 5
2x = 5 + 7
2x = 12
x = 12/2
x = 6

Respuesta.
x = 6



2(x-15) = 8x
2x - 30 = 8x
2x - 8x = 30
- 6x = 30
x = 30/-6
x = - 5

Respuesta.
x = - 5


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

Respuesta.
x = 0

Answer 2

-5(x+3)+2(x-1)= -14
-5x-15+2x-2 = -14
-5x+2x = -14+15+2
-3x = 2
x= 3/-3
X= -1
~~~~~~~~~~~~~~~~
6(-2x+5)= -18
-12x+30 = -18
-12x = -18-30
-12x = -48
X = -48/-12
X = 4
~~~~~~~~~~~~~~~~~
2(4x+1)-3(2x+3)= 5
8x+2-6x-9 = 5
2x = 5-2+9
2x =12
x= 12/2
x=6


2(x-15) = 8x
2x-30= 8x
2x -8x = +30
-6x = 30
X = 30/-6
x= -5



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