**Instructions:**

Solve a set of two equations with two unknowns and find out values of unknown variables x and y.

25 . x + 50 . y | = | 250 |

50 . x - 25 . y | = | 250 |

x | = | |

y | = | |

Correctness test | ||

25 . + 50 . | = | 250 |

50 . - 25 . | = | 250 |

25 . x + 50 . y | = | 250 |

50 . x - 25 . y | = | 250 |

x | = | 6 |

y | = | 2 |
