Please check the explanation.
Step-by-step explanation:
Given the English statement 
''The sum of two and number is less than five''.
Let us breakdown the statement.

We know that the less than symbol is denoted by '<' which is used for comparison.
Thus, the statement 'The sum of two and a number is less than five' is algebraically represented as:
Let us solve the algebraic expression.

Subtract 2 from both sides

Simplify

Thus, the solution is:

Answer:
108
Step-by-step explanation:
Since 18 x 2 = 36 you can just multiply 54 x 2. 54 x 2 =108
 
        
             
        
        
        
Given the equation :

So, to find d , divide both sides by ( -6 )
So, 

Note: when we divide two negative numbers, the result will be a positive number
