Answer:
(i) The length of AC is 32 units, (ii) The length of BC is 51 units.
Step-by-step explanation:
(i) Let suppose that AB and BC are collinear to each other, that is, that both segments are contained in the same line. Algebraically, it can be translated into this identity:
If we know that and
, then:
The length of AC is 32 units.

We need to get the variable on one side (usually the left side) and all other constants (like numbers and certain symbols like 
) on the opposite side of the variable (usually the right side).
4(2s - 1) = 7s + 12 // Our starting equation
8s - 4 = 7s + 12 // Distribute the 4 across the 2s and the -1
s - 4 = 12 // Subtract both sides by 7s
s = 16 // Add both sides by 4
The variable s is equal to 16.
4(2s - 1) = 7s + 12 // Our starting equation
8s - 4 = 7s + 12 // Distribute the 4 across the 2s and the -1
s - 4 = 12 // Subtract both sides by 7s
s = 16 // Add both sides by 4
The variable s is equal to 16.
