Answer 8

can you show me step by step

Answer 9

Sure.

Okay so lets split these equations, and solve them each individually.
First is \[2x+1\ge5\]
Subtract 1 from each side, We are trying to get x alone.
Now we have \[2x \ge4\]
Divide each side by 2, and you get
\[x \ge2\]
See ? Because 4 divided by 2, is 2.

Now the other part,
-3x>-9
We have to divide by -3, to get x alone.
So -9 divided by -3 is positive 3. Negative divided by negative = positive.
Also, the sign flips towards to other direction when you divide by a negative.
So we get x<3


Think logically, x is less than 3, or x is greater than or equal to 2. This fits into one equation. \[2\ge x >3 \]
