0.08x + 0.2y = 54

x + y = 450

Equation 1 is in the correct format.

Equation 2 is in the correct format.

1 * (0.08x+0.2y=54) --> 0.08x + 0.2y = 54

0.08 * (x+y=450) --> 0.08x + 0.08y = 36

0.08x + 0.2y = 54 - (0.08x + 0.08y = 36)

-(0.08x + 0.08y = 36)

0.2y - 0.08y = 54 - 36

0.12y = 18

y = | 18 |

0.12 |

y = 150

0.08x = 54 - 0.2y

0.08x | |

0.08 |

= |

54 - 0.2y |

0.08 |

x = | 54 - 0.2y |

0.08 |

x = | 54 - 0.2(150) |

0.08 |

x = | 54 - 30 |

0.08 |

x = | 24 |

0.08 |

x = 300

x = 300
