How to solve 3x+12-6x<-9

Mathematics

Answer:

x > 7

Step-by-step explanation:

Group the common factors, which are 3x and -6x, so it looks like:

3x - 6x + 12 < -9

-3x + 12 < -9

Subtract 12 from both sides:

-3x < -21

Divide everything by -3 to get your answer. Don't forget when dividing by a negative number, you have to flip the sign:

x > 7

Answer:

x ≈ 2.87

Step-by-step explanation:

We can subtract 6 to put the equation into a form easily solved.

x^2 +2x +1 = 15

(x +1)^2 = 15

x +1 = √15 . . . . . for the greatest solution, we only need the positive root

x = √15 -1 ≈ 2.87
