Answer:
x > -3, x >7
Step-by-step explanation:
for -2x < 6:
first divide each side by 2: -x < 3
then divide each side by -1, so the final answer is: x > -3
(whenever you divide by a negative number you have to flip the sign)
for 4x-7>21:
first, add 7 to each side: 4x>28
then divide each side by 4, and the final answer is: x >7
