Question

Which of the following is the correct solution of -2x - 3 ≥ 21?
A. x ≥ -12
B. x ≤ 12
C. x ≤ -12
D. x ≥ 12

Answer 1

You need to isolate x meaning get rid of the -2 and -3 \[-2x-3+3\ge 21+3=-2x \ge24\]
then divide both sides by -2 which means the inequality sign will flip
\[\frac{ -2x }{ -2 }\le \frac{ 24 }{ -2 }\]

Answer 2

x<12?

Answer 3

Then the answer will be \[x \le \frac{ 24 }{ -2 }\] you should be able to figure out from here

Answer 4

you dropped the negative before the 12 your answer should be negative

Answer 5

oh alright got it, thanks
