Q. Solve for x x .\newline7x501 -7 x-50 \leq-1 \quad AND 6x+70>2 \quad-6 x+70>-2 \newlineChoose 11 answer:\newline(A) x7 x \geq-7 \newline(B) 7x<12 -7 \leq x<12 \newline(C) x<12 x<12 \newline(D) There are no solutions\newline(E) All values of x x are solutions
  1. Solve First Inequality: Solve the first inequality 7x501-7x - 50 \leq -1. To isolate xx, we need to add 5050 to both sides of the inequality. 7x50+501+50-7x - 50 + 50 \leq -1 + 50 7x49-7x \leq 49 Now, we divide both sides by 7-7, remembering that dividing by a negative number reverses the inequality sign. 7x/749/7-7x / -7 \geq 49 / -7 x7x \geq -7
  2. Solve Second Inequality: Solve the second inequality -6x + 70 > -2.\newlineFirst, subtract 7070 from both sides of the inequality.\newline-6x + 70 - 70 > -2 - 70\newline-6x > -72\newlineNow, we divide both sides by 6-6, again remembering to reverse the inequality sign because we are dividing by a negative number.\newline-6x / -6 < -72 / -6\newlinex < 12
  3. Combine Solutions: Combine the solutions from Step 11 and Step 22 to find the range of xx that satisfies both inequalities.\newlineFrom Step 11, we have x7x \geq -7.\newlineFrom Step 22, we have x < 12.\newlineThe compound inequality that combines both is -7 \leq x < 12.
