Answer:  x = 6

Step-by-step explanation:

The perimeter of the isosceles triangle = 2 leg + base

Since the perimeter = 60

then 60 = 2(5x - 3) + x

       60 = 10x - 6 + x

 60 + 6 = 11x

         6 = x

Answer: x = 6

Step-by-step Explanation:

The legs are both the same so 2(5x - 3) accounts for both. Then add x and simplify.

10x - 6 + x

11x - 6

Set equal to 60

11x - 6 = 60

11x = 66

x = 6
