Solve for n:
2 n + 1 = 5
Subtract 1 from both sides:
2 n + (1 - 1) = 5 - 1
1 - 1 = 0:
2 n = 5 - 1
5 - 1 = 4:
2 n = 4
Divide both sides of 2 n = 4 by 2:
(2 n)/2 = 4/2
2/2 = 1:
n = 4/2
The gcd of 4 and 2 is 2, so 4/2 = (2×2)/(2×1) = 2/2×2 = 2:
Answer: n = 2

Inequalities are used to represent unequal expressions.
The solution set to
is: 
The inequality is given as:

From the inequality above, we have the following observation.
- The value of variable x starts from 7/16 (inclusive)
- The value of variable x has no end (i.e. infinity)
Because, 7/16 is inclusive of the values of x, we make use of the open square bracket i.e. [
We treat
, as an exclusive value. So, we make use of the close parenthesis i.e. )
Hence, the solution set is:
