Question

Find the value of x if B is the midpoint of AC

Hint:

Midpoint is the point which divides the line in two equal parts.

The correct answer is: x = 4.


    Step by step explanation:
    ○        Given:

    AB =  (x + 9)

    BC =  (4x - 3)
    ○        Step 1:
    ○        As we know, the midpoint divides the line segment in two equal parts.
    So,
    As B is midpoint of AC
    ∴ AB = BC

    rightwards double arrowx + 9 = 4x - 3

    rightwards double arrow9 + 3 = 4x - x

    rightwards double arrow12 = 3x

    rightwards double arrowx = 12 over 3

    rightwards double arrowx = 4

    • Final Answer:

    x = 4.
