Answer:
x = 3
Explanation:
If B is the midpoint of the line A to C then that means A to B and B to C are equal to one another.
Therefore, to find x you would set the 2 line equations equal to each other:
4x + 2 = 3x + 5
Move the terms around. Start by subtracting the 3x from both sides.
4x - 3x + 2 = 5
Then subtract the 2 from both sides.
4x - 3x = 5 - 2
Then combine like terms.
4x - 3x is x. 5 - 2 is 3.
So that leaves you with:
x = 3
