Question

7 fill in the blank 1 point a, b, and c are collinear. b is between a and c. 7) $ac=-3 + 6x$, $ab = 3x - 3$, and $bc = 9$. find $x$. the value of x is type your answer...

Explanation:

Step1: Set up equation using collinearity

$AC = AB + BC$

Step2: Substitute given values

$-3 + 6x = (3x - 3) + 9$

Step3: Simplify right side

$-3 + 6x = 3x + 6$

Step4: Solve for x

$3x = 9 \implies x = 3$
