If 3x2 - X + 9 = 0, what are the values of x

x = 15

Step-by-step explanation:

(3) (2) - x + 9 = 0

6 + - x + 9 = 0

(-x) + (6 + 9) = 0

combine like terms

-x + 15 = 0

subtract 15 from both sides

-x + 15 - 15 = 0 - 15

-x = - 15

Divide both sides with - 1

-x/-1 = - 15/-1

x = 15

Answer: X would have to be 15.

Step-by-step explanation:

First, 3 x 2 is 6.

Next, subtract 9 from both sides. This would make the problem now: 6 - x = - 9.

Then, subtract 6 from both sides. This makes the problem now: - x = - 15.

-x = - 15 is the same as x = 15.
