Homework Statement
Identify the solution set of the inequality.
Homework Equations
5x + 1 / x- 1 ≥ 7
The Attempt at a Solution
I multiplied both sides by x - 1 which gave me 5x+1 ≥ 7x - 7
Then I combined like terms together which gave me 8 ≥ 2x
I divided both sides by 2 which gave me 4 ≥ x.
Now that's not the answer. The answer is 1 < x ≤ 4.
Why is that?
