$42 \times 1 = 7 \times x$

42=7x

dividing both side by 7

6. Which of the following inequalities will require the inequality symbol to

Ad libitum [116K]

Answer:

Both -6x +7>-5 and 14x-2<12

Step-by-step explanation:

Your question said "Which of the FOLLOWING inequalities require the inequality symbol to be reversed when solving" I hope this means multiple choice because i got both 14x-2<12 and -6x +7>-5 to be reversed when i finished solving them. For 6x +7>-5 I got X < 2, and for 14x-2<12 I got X > -28, therefore those two are correct.
