    Since it is an equilateral triangle,

    Perimeter = 3s = 3 x side

    => 15 = 3 X (x - 2)

    => 15 = 3 (x - 2)

    => 15 = 3x - 6

    => 3x = 15 + 6

    => 3x = 21

    => x = 21/3

    => x = 7

    When x = 7,

    => Side = 7 - 2 = 5 inches

    Since, it is an equilateral triangle all sides are of 5 inches each.

    5

    Step-by-step explanation:

    We have x-2 = 5

    x-2 = 5 we separate parenthesis.

    x (-2) = 5 (+2)

    x = 7

    We can check this as what the x-2 is saying is 7-2 = 5
