Zorluk: OrtaSolving One-Variable Inequalities

Which of the following represents the solution set for the inequality below?

−3(x−2)+5x>6x−10-3(x - 2) + 5x > 6x - 10
  1. x<4x < 4Cevap
  2. B
    x>4x > 4
  3. C
    x<1x < 1
  4. D
    x>2x > 2

Cevap

The correct answer is x<4x < 4.
The correct solution is achieved by properly expanding the expression, isolating the variable xx, and correctly reversing the inequality symbol when dividing both sides by a negative number (−4-4).

Adım Adım Çözüm

1
Distribute the −3-3 into the parentheses.
−3x+6+5x>6x−10-3x + 6 + 5x > 6x - 10
Expanding the terms allows for the combination of like variables.
2
Combine like terms on the left side of the inequality.
2x+6>6x−102x + 6 > 6x - 10
Simplifying the expression makes it easier to isolate the variable.
3
Subtract 6x6x from both sides of the inequality.
−4x+6>−10-4x + 6 > -10
This step groups all variable terms onto one side of the inequality.
4
Subtract 66 from both sides.
−4x>−16-4x > -16
This isolates the variable term completely.
5
Divide both sides by −4-4 and reverse the inequality sign.
x<4x < 4
Dividing or multiplying an inequality by a negative number requires flipping the inequality direction.
