If number is equivalent to x. 
Answer is:
9•x-6/x
        
             
        
        
        
The equation is true because both sides are identical.
        
             
        
        
        

To solve for n, we have to isolate n. To do so, we move all the terms that are not n to one side of the equation, and leave n on the other side.

Equation: n + 5/16 = -1
Subtract 5/16 on both sides to bring it to the right side of the equation.


 
        
             
        
        
        
Answer: x = 6.46153846
Step-by-step explanation: 
We are given the equation <em>13x - 4 +100 = 180</em>, and we must find the value of <em>x</em>. In order to do that get x on on one side by itself and a constant on the other side by itself.
This first step is to combine like terms. <em>13x</em> is by itself. <em>-4 + 100 = 96</em>. This gives us the equation <em>13x +96 = 180</em>.
In order to get <em>x </em>by itself, subtract 96 from each side of the equation. This gives us the equation 13x = 84.
Next, divide each side by 13 to find x. This gives us x = 6.46153846




Hope this helps! Have a nice day!
