2x - 4= 0?

2x - 9= 1?

-2x = -6?

x - 8= -12?

4. (x - 3) = 0?

4x + 16 = 0?

4. (x - 6) = 3. (x - 2)?

3. y - 15 = 0?

Answer 1

Explicação passo-a-passo:

x-4=0

x= +4

x-2= 1

x= 1+2

x= 3

2x -4=0

2x = 4

x= 4/2

x= 2

2x - 9 = 1

2x= 1+9

2x = 10

x= 10/2

x= 5

-2x = -6

x= -6/-2

x= 3

x-8= -12

x= -12 +8

x= -4

4x -12=0

4x= 12

x= 12/4

x= 3

4x = -16

x= -16/4

x= -4

4x - 24= 3x -6

4x -3x = -6 +24

x = 18

3y = +15

y= 15/3

y= 5
