Model and Solve One-Variable, Two-Step Equations

The goal of solving linear equations is to: (Pick 2)

• Move the constant

• Find the value of the variable that makes the statement true

• Find the coefficient

• Combine like terms

• Isolate the variable

What is the difference between an equation and an expression?

• Algebraic expressions DO NOT have variables, but equations do

• Algebraic expressions DO NOT have an equal sign and equations do

• Expressions and equations are not different, they mean the same thing

• Algebraic expressions HAVE an equal sign and equations do not

What are the TWO basic rules for solving algebraic equations? (That means pick 2 answers)

• What you do on one side you must do to the other (keep balanced)

• Negative signs can be ignored

• Always use the opposite/inverse operations to solve

• You must start on the left side of the equation
