What is the solution set for `3\left(x+4\right)\ge2x+5`

1 answer

To solve the inequality \( 3(x + 4) \geq 2x + 5 \), we will first distribute the 3 on the left side:

\[ 3(x + 4) = 3x + 12 \]

Now, we can rewrite the inequality:

\[ 3x + 12 \geq 2x + 5 \]

Next, we will isolate \( x \) by subtracting \( 2x \) from both sides:

\[ 3x - 2x + 12 \geq 5 \]

This simplifies to:

\[ x + 12 \geq 5 \]

Now, we will subtract 12 from both sides:

\[ x \geq 5 - 12 \]

This simplifies to:

\[ x \geq -7 \]

The solution set for the inequality \( 3(x + 4) \geq 2x + 5 \) is:

\[ \boxed{[-7, \infty)} \]
