Question

X-3 ---- 2x -1 find the excluded value

Answer 1

**Refresh page if you see [ tex ]**

You mean
`(x-3)/(2x-1)`, right?

So to find excluded value, you just set denominator equal to zero;


`2x-1 = 0`

From here, you just solve for x. Add both sides by 1 then divide both sides by 2, then you would have final answer;


`\boxed{x=(1)/(2)}`

So
`(1)/(2)` is your excluded value.
