<span>6a+14=-7-a
you simplify the equation to the form, which is simple to understand 
<span>6a+14=-7-a
you move all terms containing a to the left and all other terms to the right. 
<span>+6a+1a=-7-14
you need to simplify left and right side of the equation. 
<span>+7a=-21
you divide both sides of the equation by 7 to get a. 
<span>a=-3</span></span></span></span></span>
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
We have three people 
jamal = x (since im guessing hes the youngest)
wesley= x+1
John= x+2
the formula you would use is x+x+1+x+2=108
when you simplify that you get 3X+3=108
you subtract the 3 from 108 which leaves you with 3X=105
divide that by 3 which makes x=35
so 
jamal is 35
wesley is 36
john is 37
