hello, i'm trying to solve:

6x-(2x+3) =>4x-5

i keep getting -3=>5, this can't be right.

can someone tell me what i'm doing wrong? first thing i do is distribute the negative.


( => is greator than/equal to )
 
\(\displaystyle \L
6x - (2x + 3) \ge 4x - 5\quad \Rightarrow \quad - 3 \ge - 5\)

Is that always true?
 
If you end up with a false statement, then there are no solutions.

But in this case it is true!
So it is true for every x.
The solution set is the set of real numbers.

I should have checked relapse's work before posting so quickly. Serves me right.
