You can put this solution on YOUR website!
You factor everything out. As there is a negative (or as some would say - a subtraction sign) in front of (2r+8) you have to multiply everything insided the brackets by -1, which gives us:


7r-2r-8=32


Then you add the like terms:


5r-8=32


You add 8 to each side:


5r=40


And you divide each side by 5:


r=8
