Summary of equations

Question

The sum of the measures of angle A and Angle B is 09. Angle A is 30 less than twice angle B. What are the system of equations and solve them.

Answer 1

I think that you must change the number 09 because under the conditions stated, one of those angles would have to be negative and I doubt that was intended.

 

And i will also edited your last sentence: What IS the system of equations? Solve for angles A & B.
