Answer 1

Respuesta:

Explicación paso a paso:

6x-8=4(-2x+5)

6x-8= -8x+20

6x + 8x = 20 + 8

14x = 28

x = 28/14

x = 2

3(2x-2)=2(3x+9)

6x-6 = 6x+18

6x - 6x = 18 + 6

0 = 24 ( igualdad inadecuada )

3(4x+7)=4x-25

12x+21 = 4x-25

12x - 4x = -25 - 21

8x = -46

x = -46/8

x = -23/4

7x+15=3(3x-7)

7x+15 = 9x-21

7x -9x = -21 - 15

-2x = -36

x = -36/-2

x = 18

3(Z-2)+10=(2z+2)+2

3z-6+10 = 2z+2+2

3z-2z = 2+2+6-10

z = 0

2(2x-3)=6+x

4x-6 = 6+x

4x - x = 6 + 6

3x = 12

x = 12/3

x = 4
