<span>P = (6,31°) is already a polar coordinate.
In the notation (r, </span>α) if you make r negative, it points in the opposite direction. If you add 180° to α you compensate for that.
Therefore (6,31°) = (-6,31°+180°) = (-6, 211°)
However, it is more usual to keep r positive.
Well, we would solve it as cancelling out -1/2 by multiplying it by its reciprocal (-2/1) to get x by itself, and now we'll do the same on the other side, where 6/1 times -2/1 = -12/1, which is the same as -12.
So x = -12 :3
