To solve the inequalities \( x + 2 \geq 6 \) and \( 3x \geq 6 \), we will solve each inequality separately.
-
Solve the first inequality: \[ x + 2 \geq 6 \] Subtract 2 from both sides: \[ x \geq 4 \]
-
Solve the second inequality: \[ 3x \geq 6 \] Divide both sides by 3: \[ x \geq 2 \]
Now, we need to find the intersection of the solutions to both inequalities.
The solution to the first inequality is \( x \geq 4 \), and the solution to the second inequality is \( x \geq 2 \). The more restrictive condition is \( x \geq 4 \).
Thus, the solution set is: \[ { x \mid x \geq 4 } \]
In interval notation, this is: \[ [4, \infty) \]
Final answer: \[ { x \mid x \geq 4 } \]
