Hello,
With this 2x-1/x=3/4
multiply by 4x to get:
8x^2-4=3x
Subtract 3x:
8x^2-3x-4=0
Factor using quadratic formula:
Plug the values into this to find the answers.
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+

2x-1/x=3/4
find x.

Is it too strenuous or too difficult to use parentheses to make the problem clearer?

If it's (2x - 1)/x = 3/4, then %282x+-+1%29%2Fx+=+3%2F4, but x+%3C%3E+0

4(2x - 1) = 3x ------ Cross-multiplying

8x - 4 = 3x

8x - 3x = 4

5x = 4

highlight_green%28x+=+4%2F5%29

You can do the check!!
