12, 4
take the first number together than the last ones and just find the difference
Answer:
The answer in point form is (-1,0)
(2x-20)/3 = 2x start by multiplying both sides by 3
If B is the midpoint of AC, then |AB| = |AC|.
|AB| = 3x + 2
|BC| = 5x - 10
Therefore we have the equation:
3x + 2 = 5x - 10 |subtract 2 from both sides
3x = 5x - 12 |subtract 5x from both sides
-2x = -12 |divide both sides by (-2)
x = 6
