So the equations is (6x/2) - (2x-5) And I know the answer is 13x/15 but I don’t know how you get that answer...

(6x/2) - (2x - 5) = (6x - 4x + 10)/2 = x + 5

3x-2x+5 = x + 5

That's not an equation, it's an expression, and it's equal to x + 5. The only way that can be equal to 13x/15 is if x = -37.5

That's not an equation. What's the actual problem as given?

(6x/2) - (2x-5) is an expression, not an equation. Did you mean (6x/2) = (2x-5) ?

Is there an error in your notation? The equation you gave us definitely does not come out to 13x/15. 6x/2 = 3x So 3x - (2x - 5) = 3x - 2x + 5 = x + 5 There must be an error somewhere...
