Mult. the 2nd eqn by 6 and then add this "new" equation to the 1st given eqn:

 -6x + y = -2
  6x -18y = 54
--------------------
        -17y = 52, or y = -52/17.  Subst. this value of y into either equation to find the value of x.

Cual es el volumen del cubo de rubick cuya arista mide 3 cm
Natasha2012 [34]

For this case we are asked the following question:

"What is the volume of the rubick's cube whose edge measures 3 cm"

By definition, the volume of a cube is given by:

V = l ^ 3

Where:

l: Is the side or the edge of the cube

According to the statement we have:

l = 3 \ cm

Substituting:

V = 3 ^ 3\\V = 3 * 3 * 3\\V = 27

Finally, the volume of the cube is 27 \ cm ^ 3

Answer:

27 \ cm ^ 3
