To solve the linear inequality \( 6x - 3 \geq 15 \), follow these steps:
-
Add 3 to both sides of the inequality: \[ 6x - 3 + 3 \geq 15 + 3 \] This simplifies to: \[ 6x \geq 18 \]
-
Divide both sides by 6: \[ \frac{6x}{6} \geq \frac{18}{6} \] This simplifies to: \[ x \geq 3 \]
So, the solution to the inequality is: \[ x \geq 3 \]
This means that \( x \) can be any number greater than or equal to 3.
