Solving Equations- Tatum Marshall

To multiply a sum by a number, multiply each addend by the number outside the parenthesis.

6a+7b-3

To find the value of an algebraic expression by substituting a number for a variable is called evaluate.

Inverse operations is to get a variable alone on one side of the equation in order to solve the equation.

A value in an expression that does NOT change is called a constant

if you subract the same number to both sides of an equation, the new equation will have the same solution.

5x=15

An equation does not have an equal sign.

10

if you divide the same number to both sides of an equation be the nonzero number, the equation will have same solution

The number in front of a variable

x, c, d, g

if you multiply the same number to both sides of an equation, the new equation will have a different solution

A mathematical sentence that shows that two expressions are equal.

An expression that contains at least one variable. It usually contains constants and operations.

A symbol that represents an unknown quantity.

if you add the same number to both sides of an equation, the new equation will have the same solution.

To get a variable alone on one side of the equation in order to solve the equation.

Solving is to find the value of the variable to make the equation true.

13 is a variable
