I'll give you a hint. A rectangle, a rhombus, and a square are all types of parallelograms. How many sides do they all have? Should come to you quick, good luck^^
3/3 is the equivalent to 1 ( or a whole) therefore 2/3 is less than 1. If you added another 1/3 or your 2/3, then it would be equal to 1.
2n-5=21
add 5 to both sides
2n=26
divide both sides by 2
n=13
I hope I helped! :)
