Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this.
1/5x -1/4 y = 3
2/5x + 1/2y = 2

  • Algebra -

    first one times 20
    4x - 5y = 60
    second one times 10
    4x + 5y = 20
    add them
    8x = 80
    x = 10

    in 4x + 5y = 20
    if x = 10, y = -4
