    Triangle with side Equaling:-

    Side 1 = 5-2x

    Side 2 = - 4x+9

    Since the three sides have the same length that length is

    5-2x = - 4x+9

    So, we solve for x, and then find 5-2x, the length of each side.

    5-2x=-4x=9

    5-2x = - 4x+9

    5-2x=4x-5 = - 4x+9+4x-5

    4x-2x=9-5

    2x=4

    X=2

    5-2x=5-2.2

    5-2x=5-4

    5-2x=1 is the length of each one of the three sides of this regular triangle. So the perimeter 3.2=3
