Writing Phrases as Algebraic Expression:
The variable x is usually used to represent “a number” in these expressions.
Just as a phrase ten more than five is written as 10 + 5
Or
The phrase ten more than a number is written as 10 + x
Unknown Variables:
We usually use x to represent the first number and y to represent the second number. Twice a number plus four times and other number would be written as 2x + 4y
 Negative nine times a number
 A number combined with six
 Eight take away a number
 A number shared by ten
 Two plus onehalf of a number (or a number divided by 2)
Answer Key: Unkown Variables
 x + 1y simplifies to xy
 7/xy
 xy  18
 x^{2 }10y
 6(x) + (y9)
