since it's an equilateral triangle, the sides are equal to each other.

this means that x = 5x-2

subtract x from both sides of this equation and add 2 to both sides of this equation to get:

4x = 2

divide both sides of this equation to get:

x = 2/4

each side is equal to 2/4

the perimeter is equal to 6/4 = 3/2.
