NOTES: The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown."

Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

The perimeter of a rectangle can be found by the following equation:

2L + 2W = P
OR 
P = 2L + 2W
The equation </span>P = 2L + 2W is read perimeter = 2 times Length + 2 times width

three times its width
This means 3 times w or 3w 
The w = width

perimeter is at its most 112
