Question 1140060: (3/5x -20)=(x-20)2/5
Answer by KMST(5328) (Show Source):
You can put this solution on YOUR website! I assume you mean , which I would write as
(3/5)x-20=(x-20)2/5 or 3/5)x-20=(x-20)(2/5) to avoid confusion.
The expression (3/5x -20) , means the same with or without parentheses. Those parentheses are not necessary.
To mean I would write is as (3/5)x, because sometimes 3/5x is interpreted as or .
(The lack of any symbol or space between a number or variable is interpreted as if their product is in parentheses).
Multiplying times 5, both sides of , we get the equivalent equations
,
,
, and

Then, adding to both sides, we get the equivalent equations
,
.
I hope you did not mean
, because that ends up being an uglier quadratic equation, with two ugly solutions.
