Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1
Hi.
First, I am going to give you some definitions.This will help you do the problems.
-Complementary angles have a combined sum of 90.
- Supplementary angles have a combined sum of 180.
10. 40+50=90- so YES.
12. 159+20= 179.-so NO.
Make sure you learn the definitions properly next time!
