Givens

We are given an isosceles triangle with two side measures.

We are asked to find the value of x.

You Must Know

It is important to note that in isosceles triangles, the two sides that are not the base are congruent.

Solve

Since the two sides are congruent, set them equal to each other and solve for x:

`3x-6=12\\\\3x-6+6=12+6\\\\3x=18\\\\\displaystyle (3x)/(3) = (18)/(3)\\\\x=6`

Final Answer

Therefore, x = 6.
