Answer: 1+5/7
Step-by-step explanation:
16-2r=3-r+6r+1
We move all terms to the left:
16-2r-(3-r+6r+1)=0
We add all the numbers together, and all the variables
-2r-(5r+4)+16=0
We get rid of parentheses
-2r-5r-4+16=0
We add all the numbers together, and all the variables
-7r+12=0
We move all terms containing r to the left, all other terms to the right
-7r=-12
r=-12/-7
r=1+5/7
