@Shadow
Shadow:
We know that: \[2(25x -15) + 2y = 180\] Since B and C are congruent to each other.

Since all sides are congruent to each other, all angles are congruent to each other.
CC12:
3/5+ y/25
Shadow:
We can simplify this though, with: \[3x = 180\] Since we know that three angles of the same length equal 180.
CC12:
60
Shadow:
Yeah but that's not the x we are looking for. That's just the measure of the angle.

Do you know what you would do?
CC12:
add to both sides ??
Shadow:
Since we know that all angles are 60 and we want to solve for x \[25x - 15 = 60\]
CC12:
x=3
Shadow:
Correct
