Question 260873
Assume all angles are in a triangle. we get
{{{3x + (x+4) + (2y-12) = 180}}}
step 1 - combine like terms to get
{{{4x -8 + 2y = 180}}}
step 2 - add 8 and subtract 4x from both sides to get
{{{2y = 188 - 4x}}}
here there are many values of X and Y that work.

Assume that one of the angles = another angle, for example angle 1 = angle 2, then we can say
3x = x + 4
2x = 4
x = 2
Now in angle 3, all we have is a Y, so
3 = 2y - 12
15 = 2y
y = 7.5
Here x = 2 and y = 7.5

not sure how the angles are related.
