If you add all of the marbles(10) and then chose the red(2) and make it a fraction 2/10, then reduce it by dividing the numerator and denominator by the same number (2) the the answer is C) 1:5
First you had to subtract by seventeen from both sides of equation form.

Then simplify.

Next, subtract by seven-p from both sides of equation form.

Simplify.

Then you divide by negative six from both sides of equation form.

And finally, simplify by equation.

Final answer:
