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
