Math Problem Statement

Solve for x ; -5>=(5-3x)/2<=8

Solution

To solve the inequality:

553x28-5 \leq \frac{5 - 3x}{2} \leq 8

we can break it down into two separate inequalities:

  1. 553x2-5 \leq \frac{5 - 3x}{2}
  2. 53x28\frac{5 - 3x}{2} \leq 8

Step 1: Solve the first inequality

553x2-5 \leq \frac{5 - 3x}{2}

Multiply both sides by 2 to eliminate the denominator: 1053x-10 \leq 5 - 3x

Now, subtract 5 from both sides: 153x-15 \leq -3x

Divide by -3, and remember to reverse the inequality sign because we are dividing by a negative number: 5x5 \geq x or x5x \leq 5

Step 2: Solve the second inequality

53x28\frac{5 - 3x}{2} \leq 8

Multiply both sides by 2: 53x165 - 3x \leq 16

Subtract 5 from both sides: 3x11-3x \leq 11

Divide by -3, and reverse the inequality: x113x \geq -\frac{11}{3}

Final Solution

Now we combine the two inequalities: 113x5-\frac{11}{3} \leq x \leq 5

This means the solution is: x[113,5]x \in \left[ -\frac{11}{3}, 5 \right]
