B + 9 - 2b = 6
-b = 6 - 9
-b = -3
b = 3
5(j - 4) + j = -8
5j - 20 + j = -8
6j = 12
j = 12/6
j = 2
3d - 5 - 2d = -9
d = -9 + 5
d = -4
hope this helps :)

Answer:
<h2>
AC = 21</h2>
Step-by-step explanation:
Collinear points are points are points that lies on the same line. If point B is between A and C, then AC = AB+BC
Given AC = 21x, AB = 11 and BC = 11x-1, in order to find the value of x, we will substitute the given parameters in the relationship above to have;
Subtracting 11x from both sides;
Since AC = 21x
substituting x = 1 into AC,
AC = 21(1)
AC = 21
