If the triangle is equilateral, all three sides are equal. Set any pair equal:
3x + 8 = 5x + 2 → 8 − 2 = 5x − 3x → 6 = 2x → x = 3.
Check with the third side: 7x − 4 = 7(3) − 4 = 21 − 4 = 17, same as the others.
Each side = 17, so the perimeter = 3 × 17 = 51.
3x + 8 = 5x + 2 → 8 − 2 = 5x − 3x → 6 = 2x → x = 3.
Check with the third side: 7x − 4 = 7(3) − 4 = 21 − 4 = 17, same as the others.
Each side = 17, so the perimeter = 3 × 17 = 51.
