solve by elimination method
3x+4y=4
6x+8y=8

  • algebra -

    3x+4y=4 ... (1)
    6x+8y=8 ... (2)

    If we multiply equation (1) by 2 and subtract from equation (2), we get
    0 = 0
    which means that the two equations represent coincident lines. This results in an infinite number of solutions:
    Let y=t,
    then
    x=(4-4t)/3
    y=t
    for any value of t ∈R.
