3x-23\geq -5\left(-2\right)
Multiply both sides by -2. Since -2 is negative, the inequality direction is changed.
3x-23\geq 10
Multiply -5 and -2 to get 10.
3x\geq 10+23
Add 23 to both sides.
3x\geq 33
Add 10 and 23 to get 33.
x\geq \frac{33}{3}
Divide both sides by 3. Since 3 is positive, the inequality direction remains the same.
x\geq 11
Divide 33 by 3 to get 11.
