Resuelve los siguientes problemas!! Hallar el valor de la "X" en:

Answer 1

Respuesta:

Explicación paso a paso:

12x -5 /3 = x+ 10

12x - 5 = 3(x+10)

12x - 5 = 3x +30

12x - 3x = 30 +5

9x = 40

x = 40/9

4x -1/3 = x

4x - 1= 3 ( x)

4x - 1 = 3x

4x - 3x = +1

x = 1

6x-9/9=3

6x -9= 9(3)

6x - 9 = 27+ 9

6x = 36

x = 36/6

x= 6

3x+1/2=11

3x +1 = 2(11)

3x = 22 -1

3x = 21

x = 21/3

x = 7
