    x = 6

    Step-by-step explanation:

    Givens

    There are 3 sides. All are equal to (4x - 3)

    Their sum = 63

    Formula

    3 (4x - 3) = 63

    Solution

    3 (4x - 3) = 63 Divide by 3 12x - 9 = 63 Add 9 to both sides 12x = 63 + 9 12x = 72 Divide by 12 x = 72/12

    x = 6 Answer
