2b + 3t = 80

b + t = 34

Equation 1 is in the correct format.

Equation 2 is in the correct format.

1 * (2b+3t=80) --> 2b + 3t = 80

2 * (b+t=34) --> 2b + 2t = 68

2b + 3t = 80 - (2b + 2t = 68)

-(2b + 2t = 68)

3t - 2t = 80 - 68

1t = 12

t = | 12 |

1 |

t = 12

2b = 80 - 3t

2b | |

2 |

= |

80 - 3t |

2 |

b = | 80 - 3t |

2 |

b = | 80 - 3(12) |

2 |

b = | 80 - 36 |

2 |

b = | 44 |

2 |

b = 22

b = 22
