    well, this is a algebraic problem... given the length of AC=32, from the figure the length of AB=2x and BC=2x+8. doesnt AC=AB+BC ? just to add both lines, to make an expression algebraic and solve for x. its solution like in figure :)

    1) Segment addition and definition of between 2)substitution with given information 3) simplifying 2x + 6x = x(2 + 6) = 8x , it sorta an distribute thing 4)subtraction property of equality ( subtracted 8 both sides) 5)division property of equality ( multiplicative inverse property) (divide by 8 on both sides)

    AB+BC=AC, put the values of them : 2x+6x+8=32, simplify it 8x+8=32, add -8 from both sides 8x+8-8=32-8,simplify it 8x=24, divide both sides by 8 8x/8 = 24/8, solve for x x=3
