Answer

\( y \leq -\frac{31}{2} \)

Solution

Solve the equation \( \frac{y+3}{5} \geq \frac{y+2}{3}+2 \). Solve the inequality by following steps: - step0: Solve for \(y\): \(\frac{y+3}{5}\geq \frac{y+2}{3}+2\) - step1: Multiply both sides: \(\frac{y+3}{5}\times 15\geq \left(\frac{y+2}{3}+2\right)\times 15\) - step2: Multiply the terms: \(3y+9\geq 5y+10+30\) - step3: Simplify: \(3y+9\geq 5y+40\) - step4: Move the expression to the left side: \(3y-5y\geq 40-9\) - step5: Add and subtract: \(-2y\geq 40-9\) - step6: Add and subtract: \(-2y\geq 31\) - step7: Change the signs: \(2y\leq -31\) - step8: Divide both sides: \(\frac{2y}{2}\leq \frac{-31}{2}\) - step9: Divide the numbers: \(y\leq -\frac{31}{2}\) The solution to the inequality \( \frac{y+3}{5} \geq \frac{y+2}{3}+2 \) is \( y \leq -\frac{31}{2} \).

The Deep Dive

To solve the inequality \( \frac{y+3}{5} \geq \frac{y+2}{3}+2 \), let's start by getting rid of the fractions. First, find a common denominator, which in this case is 15. Multiply every term by 15: \[ 15 \cdot \frac{y+3}{5} \geq 15 \cdot \left(\frac{y+2}{3} + 2\right) \] This gives: \[ 3(y+3) \geq 5(y+2) + 30 \] Now, distribute: \[ 3y + 9 \geq 5y + 10 + 30 \] Combine like terms: \[ 3y + 9 \geq 5y + 40 \] Now, isolate \(y\) by getting all the \(y\) terms on one side and constants on the other: \[ 9 - 40 \geq 5y - 3y \] This simplifies to: \[ -31 \geq 2y \] Now, dividing by 2, remember to flip the inequality sign since we're dividing by a negative number: \[ y \leq -\frac{31}{2} \] Thus, the solution to the inequality is \( y \leq -15.5 \).
