39=9x+7-3x+20
Subtract 27 from each side
12=6x
2=x
Now plug in 2 for x to find AB and BC
9x+7= AB
9(2)+7=AB
18+7= AB
25= AB
-3x+20= BC
-3(2)+20= BC
-6+20= BC
14= BC
I always found it easiest to draw out the picture
Slope can be found but putting the equation in slope intercept form (y=mx+b)
6y=3x-12
y= 0.5x-2
M is your slope, b is the y intercept.
So the slope is 1/2, yintercept is (0,-2)
Hope this helps
