given that line f is parallel to line g, find the value of x. the diagram is not to scale

3x=6x+45
A. 16
B. -15
C. 15
D. 14

To find the value of x, we first need to simplify the equation:

3x = 6x + 45

Subtract 6x from both sides:

-3x = 45

Now, divide by -3 to solve for x:

x = -45 / 3
x = -15

Therefore, the value of x is -15. So, the answer is:

B. -15
