c)x/3 + x=x/2=
d)x/2+x+1/3=2=​

Answer 1

Respuesta:

a) x = -3/10

b) x = - 12/5

c) x = 0

d) x = 10/9

Explicación paso a paso:

1. x + 1/2 + x = x/3

        1/2 +2x = x/3

        1/2 = x/3 - 2x

        1/2 = -5x/3

        (1)3 =(-5x)2

        3 = -10X

        10x = -3

       X = -3/10

  2. x/2 - x/3 = x +2

     x/6 = x+2

     x=6x +12

    -12 = 5x

    X = -12/5

3. x/3 + x=x/2

    4x/3 = x/2

     (4x)2 =(x)3

    8x = 3x

   5x = 0

  X = 0

4.  x/2+x+1/3=2

 3x/2 = 2-1/3

  3x/2 = 5/3

  9x=10

X = 10/9
