# Yr 8 Linear Equation

### Linear Equations

Question | Answer |
---|---|

Sequence | A series of numbers that follow a particular pattern or rule |

Term | Each number in the sequence |

Equation | Links to expressions with an equal sign |

Expression | Does not have an equal sign |

The inverse operation to addition is | The inverse (opposite) to addition is subtraction |

The inverse operation to multiplication is | The inverse (opposite) to multiplication is division |

Flowchart | Can be used to represent a series of operations |

Input | Is referring the first box in a flowchart |

Output | Is referring to the last box in a flowchart |

Backtracking | To work backwards using inverse operations to find the input number |

Linear equation | Is an equation where the variable/pronumeral has an index (power) of one. Does not contain squared or square roots |

Variable | A letter or symbol in an equation or expression that may take on different values |

Pronumeral | A letter used in place of a number Another name for variable |

To solve an equation | By doing the same to both sides Must always keep the equation balanced "What ever you do to the LHS you must do to the RHS" |

To make the equation true... The LHS= | must =RHS |

If you have unknowns 'pronumerals' on both sides of the equation | You need to get all pronumerals onto the one side. Usually moving the smaller coefficient |

Coefficient | The number in font of the pronumeral. |
