x = 2
Step-by-step explanation:
6 - 4x = 6x - 8x + 2
6 - 2 - 4x = 6x - 8x

4 = 2x
4/2 = x
2 = x
therefore x = 2
perimeter of a triangle ABC
Perimeter of a Triangle
= AB + BC + CA
= 10cm + 8cm + 12cm,
(add the length of each side of the triangle).
= 30cm
Perimeter of the triangle = Sum of the sides.
