16%2B8r-4r%2B4=24 Start with the given equation.


4r%2B20=24 Combine like terms on the left side.


4r=24-20 Subtract 20 from both sides.


4r=4 Combine like terms on the right side.


r=%284%29%2F%284%29 Divide both sides by 4 to isolate r.


r=1 Reduce.

Solutions:
16 + 8r - 4r + 4 = 24
16 + 4r + 4 = 24
20 + 4r = 24
20 - 20 + 4r = 24 - 20
4r = 4
Dividing both sides by 4, we get
4r/4 = 4/4
r = 1
