X=2
Y=4
Multiply top so y values cancel out, so multiple top by -3. Y values cancel out. You combine top and bottom equations, x=2. Plug 2 in first equation for x. Y=4

Answer:
2/4 
Step-by-step explanation:
half/whole for any number really
 
        
             
        
        
        
6ax is a common factor, so divide top and bottom by 6ax:
(a-3x+7ax)/6ax.
Divide each of the terms in the numerator by the denominator:
1/6x-1/2a+7/6
        
             
        
        
        
Answer:
16 - 6n
Step-by-step explanation:
10 , 4 , -2 , - 8 .....
This is arithmetic sequence
first term = 10
Common difference = 2nd term - first term
                           d    = 4 - 10
                             d = -6
nth term = a₁ + (n -1)d
               = 10 + (n - 1)*(-6)
              = 10 + n*(-6) - 1*(-6)
              = 10 - 6n + 6
              = 10 + 6 - 6n
              = 16 - 6n
