Your question: simplify 28r-q(2r+6)
Just so you know: I have a feeling that the "28" is a fraction, so the first answer was for the original question; and the second is for if the equation's a fraction.
Answer:(Original question) -2qr - 6q + 28r
Answer: (If it's a fraction) -2qr - 6q + 1/4
I hope this helps, if you need any more explanation; I'm willing to do so, mate.
