Question 227055
the triangle has three equal angles, so it also has three equal sides


8 = 3x + y = x + 3y + 2


3x + y = 8 ___ y = 8 - 3x


x + 3y + 2 = 8 ___ x + 3y = 6


substituting ___ x + 3(8 - 3x) = 6 ___ x + 24 - 9x = 6 


24 - 8x = 6 ___ 18 = 8x ___ 9/4 = x


substituting ___ y = 8 - 3(9/4) = 5/4
