The correct Answer is:
To solve the inequality \( 37 - (3x + 5) \geq 9x - 8(x - 3) \), we will follow these steps: ### Step 1: Simplify both sides of the inequality Start by distributing and simplifying the left and right sides of the inequality. Left side: \[ 37 - (3x + 5) = 37 - 3x - 5 = 32 - 3x \] Right side: \[ 9x - 8(x - 3) = 9x - 8x + 24 = x + 24 \] Now, the inequality becomes: \[ 32 - 3x \geq x + 24 \] ### Step 2: Rearrange the inequality Next, we will move all terms involving \(x\) to one side and constant terms to the other side. Add \(3x\) to both sides: \[ 32 \geq x + 3x + 24 \] \[ 32 \geq 4x + 24 \] Now, subtract \(24\) from both sides: \[ 32 - 24 \geq 4x \] \[ 8 \geq 4x \] ### Step 3: Solve for \(x\) Now, divide both sides by \(4\): \[ \frac{8}{4} \geq x \] \[ 2 \geq x \] or \[ x \leq 2 \] ### Step 4: Write the solution set The solution set for the inequality \(x \leq 2\) can be expressed in interval notation as: \[ (-\infty, 2] \] ### Final Answer Thus, the solution set of the inequality is: \[ x \in (-\infty, 2] \]
