Tommy, please confirm if the following is correct.
(You need to type grouping symbols to clearly show what's in denominators.)
\(\displaystyle \frac{2}{x} \ = \ \frac{4}{5x + 2}\)
If this is correct, then here is how we type it:
2/x = 4/(5x + 2)
So, the denominators are x and 5x+2.
Set them equal to zero and solve, if you want to find the value of x that makes them zero.
(Is one of those answers obvious?)
To solve this equation, you can begin by cross-multiplying. That will get rid of the ratios and provide you with a quadratic equation.
Please start including some statements in your posts about what you've tried or why you're stuck.
