### Pre-Algebra - Ch. 7

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

3y - 20 = 8y | y = -4 |

y - 7 = 2y - 6 | y = -1 |

5y + 8 = 7y | y = 4 |

3y = y + 22 | y = 11 |

2y + 6 = -y - 8 | y = -4 2/3 |

4y + 8 = 6y - 4 | y = 6 |

y + y + y = y + 6 | y = 3 |

y + y + 18 = 4y | y = 9 |

2(y - 4) = 3y | y = -8 |

7y = 2(y - 10) | y = -4 |

5(y - 3) = 2y - 6 | y = 3 |

4(8 - y) = 2y + 16 | y = 2 2/3 |

2y = 4(y - 8) | y = 16 |

3(y + 7) = 10y | y = 3 |

1/2(4y - 2) = y + 5 | y = 6 |

20.6 + 2.1y = -8.2y | y = -2 |

-2(y + 6) = y + 3 + 2y | y = -3 |

6(y + 3) = -2(y + 31) | y = -10 |

7y - 4 + 2y = 3y - 2 | y = 1/3 |

3(2y - 0.3) = 19.4 - y | y = 2.9 |
