Solving Equations

1
Solving Equations

• Using Adding or Subtracting

2
Equations

• Let y 5

3
Equations

• Let y 5

This is a true equation
4
Equations

• The value for a variable that makes an equation a
  true sentence is the solution to the equation

5
Objective

• Use inverse operations to solve equations

6
Inverse Operations

• Inverse operations undo each other

7
Inverse Operations

• Inverse operations undo each other
• To undo Addition you Subtract
• To undo Subtraction you Add
• To undo Multiplication you Divide
• To undo Division you Multiply

8
Inverse Operations

• When we undo operations we work backwards to
  solve an equation
• Equations must remain balanced
• GOAL!!
• To get the variable alone on one side of the
  equation
• B 25
