Zorluk: KolaySolving One-Variable Inequalities

The solution to the one-variable inequality −2x>10-2x > 10 is x>−5x > -5.

Cevap: Cevap

Cevap

False
The correct answer is False because isolating xx requires dividing by −2-2, which means the greater-than sign (>>) must flip to a less-than sign (<<). The actual mathematically correct solution is x<−5x < -5.

Adım Adım Çözüm

1
Divide both sides of the inequality by −2-2.
−2x−2\frac{-2x}{-2} and 10−2\frac{10}{-2}
To isolate the variable xx on one side of the inequality.
2
Reverse the inequality symbol.
x<−5x < -5
When dividing or multiplying an inequality by a negative number, the direction of the inequality symbol must be flipped to maintain a mathematically true statement.
