BRAINLIEST WILL I GIVE HURRY

Mathematics
1 answer:
stepladder [879]3 years ago
4 0

Answer:

{10,8}

Step-by-step explanation:

-3x + 4y = -62

4x + 5y = 0

let's eliminate the x

-3x + 4y = -62 | x -4 |

4x + 5y = 0 | x 3 |

12x - 16y = 248

12x + 15y = 0

-------------------- -

-31y = 248

y = 248/(-31) = 8

since you must do this proble with elimination, we cant use subtitution. so we repeat the way once more to find x (eliminate y)

-3x + 4y = -62 | x 5 |

4x + 5y = 0 | x 4 |

-15x + 20y = -310

16x + 20y = 0

-------------------- -

-31x = -310

x = -310/-31 = 10
