Question

Please help me!!!!................

Answer 1

y = 12

Explanation:

`\text{If}\ \overrightarrow{BD}\ \text{is the angle bisector of}\ \angle ABC,\ \text{then we have the equation:}\\\\3y+6=5y-18\qquad\text{subtract 6 from both sides}\\3y=5y-24\qquad\text{subtract 5y from both sides}\\-2y=-24\qquad\text{divide both sides by (-2)}\\\boxed{y=12}`

Answer 2

I'll try to help

It is a bisector so the two equations with Y are congruent

3y+6=5y-18

2y=24

y=12

Hope I did it right...
