Question

12x+4y=1
6x-2y=3 substitution, elimination, or graphing ?

Answer 1

y = -5/8

x = 7/24

Explanation:

elimination

12x + 4y = 1 | ×1 |

6x - 2y = 3 | ×2 |

12x + 4y = 1

12x - 4y = 6

_________--

8y = -5

y = -5/8

elimination

12x + 4y = 1 | ×1 |

6x - 2y = 3 | ×2 |

12x + 4y = 1

12x - 4y = 6

_________+

24x = 7

x = 7/24
