Original: If the angles are congruent, then the measures of the angles are equal. What is this statement called: If the measures of the angles are not equal, then the angles are not congruent.

Sry i’m so bad at math! wish i could answer #imdumb

Iwould say always for the both of them

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
