You use the formula y=mx+b, therefore you have to isolate the y
First you subtract 3x to both sides. 
3x - 5y = -35
-3x -3x
Then it would be 
-5y = -3x -35
Then you divide -5 on both sides to isolate the y
-5y = -3x -35
/-5 /-5 /-5
Two negatives cancel out and make a positive so it would be
Y = 3/5x + 7

Answer:
x=16°
y=25°
Step-by-step explanation:
7x=112
x=112/7
x=16
90+y=115
y=115-90
y=25
 
        
                    
             
        
        
        
The distance between -2 and -1 1/2 is 1/2:
-2+1/2=-1 1/2
-1 1/2 =-1 1/2
I was trying to show my work but hope this could help you
