(sorry I don't understand your language but, here's my answer)
- a/12 + 2/3(b) = ?
- a = 5, b = -4
- 5/12 + 2/3(-4)
- 5/12 + 2/-12

The solution to the answer is as follows:
<span>x - y = 1...[1],
 
2x + y = 19...[2], {[1]+[2]}---> 3x = 30,
 
ie., x = 10. C is correct answer.

I hope my answer has come to your help. God bless and have a nice day ahead!
        
                    
             
        
        
        
Answer:
x=5
Step-by-step explanation:
The angles of a trangle have to add up to 180 degrees. With that information, we can create an equation:
27+98+(10x+5)=180
125+10x+5=180
130+10x=180
-130         -130
______________
10x=50
/10   /10
x=5
