First move the (Y) to the other side of the equal sign,

Then subtract add (15) on both sides

Since a variable can't be negative just divide by (-1) on both sides,

The answer would be,

Hope this helped

Step-by-step explanation:
Law of sine:  =
= 
 
93*14=25x
1302=25x
52.08=x
 
        
             
        
        
        
<span>2t-7-5t=11
Start by combing like terms:
2-5t=-3t  
Now we have: 
-3t-7=11  
Add 7 to both sides
-3t=18
To isolate t we divide both sides by -3 
Final answer: 
t=-6 </span>
