Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this. 14x + 18y = -54,-4x – 14y = 42

  • Intermediate Algebra -

    14x + 18y = -54
    -4x – 14y = 42

    multiply top by 2, bottom by 7, and add:

    28x + 36y = -108
    -28x - 98y = 294

    -62y = 186
    y = -3
    so, x = 0
