let the software do the rest.



 
Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:

  We'll use substitution. After moving 1*y to the right, we get:

  , or . Substitute that

  into another equation:

   and simplify: So, we know that y=43. Since , x=137.

  

  Answer: .

  







another method



let x be the smaller angle then 8+3x will be the large angle.
