a + s = 175

8a + 5s = 1028

Equation 1 is in the correct format.

Equation 2 is in the correct format.

8 * (a+s=175) --> 8a + 8s = 1400

1 * (8a+5s=1028) --> 8a + 5s = 1028

8a + 8s = 1400 - (8a + 5s = 1028)

-(8a + 5s = 1028)

8s - 5s = 1400 - 1028

3s = 372

s = | 372 |

3 |

s = 124

1a = 175 - 1s

a = | 175 - 1s |

1 |

a = | 175 - 1(124) |

1 |

a = | 175 - 124 |

a = | 51 |

a = 51

a = 51
