Solving Algebraic Expressions with One Variable Two Terms

Which property allows you to group terms in an algebraic expression without changing the result?

• Commutative property

• Associative property

• Identity property

• Distributive property

A letter or symbol that represents a missing number or unknown value. Generally, the letter is lowercase and italicized.

• Operation

• Variable

• Exponent

• Term

A mathematical expression that contains one or more variables.

For example:  4x + 3

• Numerical Expression

• Verbal Expression

• Algebraic Expression

• Radical Expression

The number in front of a variable. The number is being multiplied by the variable.

For example, in the expression 7x, the “7.”

• Coefficient

• Constant

• Like Terms

• Variable

The operation that reverses or "undoes" the effects of another operation. These are used to isolate a variable when solving equations.

• Reciprocal Operations

• Identity Operations

• Opposite Operations

• Inverse Operations

Terms that have the same variable and exponent factors. These type of terms can be combined.

• Like Terms

• Variables

• Coefficients

• Expressions

A value, or values, we can put in place of a variable (such as x) that makes the equation a TRUE statement.

• Solution

• Input

• Output

• Example

A mathematical sentence or statement relating to two equal quantities. When written in mathematical notation, it always contains an equal sign.

For example:  4x + 3 = 11

• Expression

• Inequality

• Operation

• Equation

Solve for x

3.5x = 7.49

• 2.14

• 3.99

• 10.99

• 26.215

When solving for 't' in the equation 3t = 9, you should ___________ each side by 3.
