Hello, my instructions are to solve for x for this equation:
(4/5x)+(1/10) = (13/2x) + (7/5x)
The LCD is 10x and then Webwork says to multiply both sides by 10x to obtain an equivalent equation without fractions. And I'm not supposed to add or subtract anything from both sides yet. It's a step-by-step problem. Any help would be appreciated!!

You have parentheses in the wrong places and they're optional for the second fraction:

4/(5x) + 1/10 = 13/(2x) + 7/(5x)


\(\displaystyle \dfrac{10x}{1}\cdot\dfrac{4}{5x} \ + \ \dfrac{10x}{1}\cdot\dfrac{1}{10} \ = \ \dfrac{10x}{1}\cdot\dfrac{13}{2x} \ + \ \dfrac{10x}{1}\cdot\dfrac{7}{5x}\)


Can you do the next step?
