Given the numerical equation:

16 - 2r = -3r + 6r + 1

Solve for r.

Solution:

In order to solve for r, we simply need to combine similar terms first.

16 - 2r = -3r + 6r + 1

16 - 2r = 3r + 1

Transpose -2r and 1 to the opposiste sides of the equation, hence we must take note that in transposing a number, the sign changes.

16 -1 = 3r + 2r

15 = 5r

Divide both sides by 5 in order to cancel out 5r, leaving behind r.

5r/5 = 15/5

r = 3

Final answer:

r = 3
