Answer:

[tex]y = 4[/tex]

Step-by-step explanation:

Given

[tex]ABD = 2y[/tex]

[tex]CBD = 5y - 12[/tex]

Required

Find y ---Missing part of the question

Since BD bisects ABC;

This implies that

[tex]ABD = CBD[/tex]

This is so because a bisector splits a segment into equal parts;

Substitute values for ABD and ABC

[tex]2y = 5y - 12[/tex]

Collect Like Terms

[tex]2y - 5y= - 12[/tex]

[tex]-3y = -12[/tex]

Divide  both sides by -3

[tex]y = 4[/tex]

Hence;

The value of y is 4
