Full solution

Q. Solve for qq.\newline1(q17)+1220-1(q - 17) + 12 \leq 20
  1. Distribute 1-1: Distribute 1-1 across the parentheses in the inequality 1(q17)+1220-1(q - 17) + 12 \leq 20.
    1×q+(1)×(17)+1220-1 \times q + (-1) \times (-17) + 12 \leq 20
    1q+17+1220-1q + 17 + 12 \leq 20
  2. Combine like terms: Combine like terms on the left side of the inequality.\newline1q+17+12=1q+29-1q + 17 + 12 = -1q + 29\newlineSo, 1q+2920-1q + 29 \leq 20
  3. Subtract 2929: Subtract 2929 from both sides of the inequality to isolate the term with the variable qq.
    1q+29292029-1q + 29 - 29 \leq 20 - 29
    1q9-1q \leq -9
  4. Divide to solve: Divide both sides of the inequality by 1-1 to solve for qq. Remember to reverse the inequality sign when dividing by a negative number.\newline1q/19/1-1q / -1 \geq -9 / -1\newlineq9q \geq 9
