Solve 5−2x3≤x6−5\frac{5-2 x}{3} \leq \frac{x}{6}-5.

Answer: x≥8x \geq 8

Step-by-step solution

Step 1: Clear the denominators

To eliminate the denominators and simplify the inequality, we multiply both sides by the least common multiple (LCM) of the denominators, which are 3 and 6. The LCM of 3 and 6 is 6.

Step 2: Simplify the inequality

After multiplying by 6, we simplify each term. On the left side, 6/3=26/3 = 2, so we have 2(5−2x)2(5-2x). On the right side, 6/6=16/6 = 1, so we have xx, and 6×5=306 \times 5 = 30.

Step 3: Distribute and combine like terms

Next, we distribute the 2 on the left side: 2×5=102 \times 5 = 10 and 2×(−2x)=−4x2 \times (-2x) = -4x. Now, we have a linear inequality with no fractions.

Step 4: Isolate the variable term

To isolate the variable xx, we move all terms containing xx to one side and constant terms to the other. We add 4x4x to both sides and add 3030 to both sides.

Step 5: Simplify and solve for x

Combine the terms on both sides: 10+30=4010 + 30 = 40 and x+4x=5xx + 4x = 5x. Finally, divide both sides by 5 to solve for xx. Since we are dividing by a positive number, the inequality sign remains the same.
