Answer:
x = 3
Step-by-step explanation:
3(x + 2) = 6(x - 1) + 3
Divide both sides by 3.
x + 2 = 2(x - 1) + 1
Distribute the 2 on the right side.
x + 2 = 2x - 2 + 1
Combine like terms on the right side.
x + 2 = 2x - 1
Add 1 to both sides. Subtract x from both sides.
3 = x
x = 3

Answer:
   C. y is 6 less than x
Step-by-step explanation:
It is not hard to check.
   A. 6 times x is 6×8 = 48, not 2
   B. 6 times y is 6×2 = 12, not 8
   C. 6 less than 8 is 2; 6 less than 9 is 3
   D. 6 more than 8 is 14, not 2

The relation described in C matches the table.
 
        
             
        
        
        
n=2
8+8(8-n)=40+8n (distribute 8 through the parenthesis)
8+64-8n=40-8n (add the numbers)
<em>72-</em>8n=40+8n (move the variable to the left side and change its sign)
<em>72</em><em>-</em>8n+8n=40
-8n+8n=40<em>-72</em> (connect like terms)
-16n = -32 (divide both sides by -16)
<u><em>n=2</em></u>
