Answer:
x=8
Step-by-step explanation:
2x-6+4=14
Combine like terms
2x-2=14
Add 2
2x=16
Divide
x=8
Checking work)
2(8)-2=14
16-2=14
14=14
 
        
                    
             
        
        
        
Y = 3
Just simplify the both sides, then add 7y to both  then add 8 to both sides and divide both sides by 15
