(r,theta) represents polar coordinate .
And in (r,theta), there is neither any restriction on r nor on theta. It means both r and theta can either be positive or negative .
For e.g. (2,30 degree), (2,-30 degree) both are correct .
So the given statement is true .

Work Shown:
-------------
Side note:
A similar formula is 
We can isolate the last term to get the first equation shown above.
Equation 1) y=x+3
Equation 2) y=2x+5
Rearrange both equations so that (x) and (y) are on the same side.
1) -x+y=3
2) -2x+y=5
Subtract equations with each other.
x=-2
Plug in -2 for (x) in equation 1.
y=(-2)+3
Simplify.
y=1
(-2, 1)
