How do you translate $x + 9$ into words?

Hint: An equation is defined as a statement in maths in which two expressions are equated to each other. There are basically two expressions, one on each side with an equal sign in between. An expression nothing but, a number, a variable or a combination of numbers and variables and operation symbols.

Complete step by step answer:
In order to solve any question, first we need to convert the word equation into an algebraic equation. The main aim of solving any kind of algebraic expression in an equation is to find out the variable which is unknown to us. When any of the two expressions are equated, then they form an equation, and thus, it becomes easier to solve and find out the unknown terms in the given question.

The expression $x + 9$ can simply be written in words as $x$ plus $9$. This is the most basic form of representing an algebraic equation into a word equation. There are various other ways in which we can translate $x + 9$ into words. Some of them are as follows:
(A) the sum of $x$ and $9$
(B) $x$ increased by $9$
(C) $9$ more than the variable $x$
(D) the total of $x$ and $9$
(E) $9$ added to $x$
(F) the variable $x$ raised by $9$

Note: Algebraic expressions are the expressions that play an important role in the mathematics curriculum and in mathematics in general. Algebra and its expressions are considered to be the most important language of mathematics, and are basically used to describe relationships which are present between people, thoughts, elements and structures.
