Math Problem Statement

8\left(6x+5\right)+2\ge2x+7

Solution

Let's solve the inequality step by step.

Given inequality: 8(6x+5)+22x+78(6x + 5) + 2 \ge 2x + 7

Step 1: Distribute the 8 on the left-hand side.

8×6x+8×5+22x+78 \times 6x + 8 \times 5 + 2 \ge 2x + 7 48x+40+22x+748x + 40 + 2 \ge 2x + 7

Step 2: Combine like terms on the left-hand side.

48x+422x+748x + 42 \ge 2x + 7

Step 3: Subtract 2x2x from both sides to move the terms involving xx to one side.

48x2x+42748x - 2x + 42 \ge 7 46x+42746x + 42 \ge 7

Step 4: Subtract 42 from both sides to isolate the term with xx.

46x74246x \ge 7 - 42 46x3546x \ge -35

Step 5: Divide both sides by 46 to solve for xx.

x3546x \ge \frac{-35}{46}

Step 6: Simplify the fraction if possible.

x3546x \ge \frac{-35}{46} The fraction 3546\frac{-35}{46} cannot be simplified further, so the solution is: x3546x \ge \frac{-35}{46}

This is the final answer.
