Let the number be x.
8 - x = x -34
2x = 8 + 34
2x = 42
x = 21
Answer: The number is 21.
        
             
        
        
        
Answer:
3 and 18
Step-by-step explanation:
let x be the first number
let 6x be the second number
x + 6x = 21
7x=21
x=21/7
x=3
second number =6x
second number 6x3= 21
 
        
             
        
        
        
C - T = T would be the correct answer
        
             
        
        
        
Answer:
4x-11=5
Step-by-step explanation:
If u were to divide each side of the equation by 2, the 2 on the left which is supposed to distribute into the parenthesis would disappear, and the 10 on the right side would turn into 5.
What is left is this,
4x-11=5
 
        
             
        
        
        
Answer:
No. 
Step-by-step explanation:
To determine if (0,0) is a solution to the inequality, substitute 0 for x and 0 for y and check to see. Thus: 

Substitute 0 for x and 0 for y: 

Multiply: 

Subtract: 

So, (0,0) is <em>not</em> a solution. 
And we're done!
