    Answer:

    c

    Step-by-step explanation:

    First, I’ll isolate the x in x+4y=5 to match with the other equation.

    The new equation would be x= -4y+5

    Next, we will multiply one equation by 3 and the other by -1 for both to match with the other.

    -1(-12y + 15 = 3x )

    3(-4y + 5 = x)

    The new equations would be :

    12y – 15 = -3x

    -12y + 15 = 3x

    Add the equations and you get

    0 = 0

    The equation has an infinite amount of solutions
