Solving One-Step Equations by Adding or Subtracting Lesson 9.02
Objectives I can state and understand the three key ideas for solving algebraic equations I can state and understand the four steps of solving simple algebraic equations I can solve one-step equations by adding or subtracting
Note!!! Left hand side Right hand side LHS RHS
Note!!! An algebraic equation is an equation with at least one variable.
Algebra Three Key Ideas
Key Ideas Given any Algebraic equation, to find the solution, get the variable by itself. 1
Key Ideas Whatever you do to one side, do to the other side 2
Investigate 2. Whatever you do to one side, do to the other side
Investigate 2. Whatever you do to one side, do to the other side
Investigate 2. Whatever you do to one side, do to the other side
But…
Investigate 2. Whatever you do to one side, do to the other side
Key Ideas Given any Algebraic equation, to find the solution, get the variable by itself. 2. Whatever you do to one side, do to the other side
Key Ideas Inverse operations undo each other, they “get rid of” parts of the equation. To get rid of something, do the inverse. 3
What are Inverse Operations The inverse of addition is subtraction The inverse of subtraction is addition The inverse of multiplication is division The inverse of division is multiplication
