Algebra practice question

Answer: A. x < 3

Subtract 7: −2x > −6. Divide by −2 and flip: x < 3.

Why the other answers are wrong

B. x > 3

x > 3 forgets to flip the inequality when dividing by a negative.

C. x < −3

x < −3 divides −6 by 2 instead of −2 (sign error).

D. x > −4

x > −4 adds 7 instead of subtracting it and doesn't flip.
