Question

Solve the inequality. 6x + 6 < 4x ? 3 A) x < 3 2 B) x < 9 2 C) x < ? 3 2 D) x < ? 9 2

Answer 1

x < -3

Explanation:

6x + 6 < 4x subtract 6 from both sides

6x + 6 - 6 < 4x - 6

6x < 4x - 6 subtract 4x from both sides

6x - 4x < 4x - 4x - 6

2x < -6 divide both sides by 2

2x : 2 < - 6 : 2

x < -3

Answer 2

-3 > x

Explanation:

6x + 6 < 4x

Subtract 6x from each side

6x -6x+ 6 < 4x-6x

6<-2x

Divide by -2. Remember that flips the inequality.

6/-2 > -2x/-2

-3 > x
