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

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.

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

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
