Question 886251

Here is my question. I KNOW the first formula, but I want to REVERSE it.

Width	W	28	 					
length	L	40	 					
weight	Wt	50	 					
factor 1	F1	2	 					
factor 2	F2	950	 					
Answer	Y	 	 					
									
Solving for Y						
(W x L	x Wt x F1)  /  F2 =  Y	
so....		 							
									
Solution							
(28 x  40 x 50  x  2)  / 950	=118	
							 	
								
 	 	 	 	 	 	 	 	 	 
Now I want to solve it when I don't know Wt (curretnly holding the place as "50")
 									 
(28 x 40 x Y x 2)/ 950	=118	 
 			 				 
 	 	 	 	 	 	 	 	 	 

How do I set up/reverse the formula?
(asks this grown up who hasn't had Algebra in 35 years)

Thank you!
<pre>
Your formula is: {{{(W * L * Wt * F[1])/F[2] =  Y}}}
You can solve the equation for Wt, then plug in values for W, L, {{{F[1]}}}, {{{F[2]}}}, and Y to determine the value of Wt, OR
You can just substitute all values for all known variables to determine the value of the unknown variable. 
Note that in your attempt to determine the value of Wt, you would not get: {{{(28 * 40 * Y * 2)/950 = 118}}}, but {{{(28 * 40 * Wt * 2)/950 = 118}}} instead.
This will give you the value of Wt, but since Y was actually ROUNDED to 118, you would not get a value of exactly 50
for Wt.
If you need a complete and detailed solution, let me know!!
