Question

What is the answer to the question?​

Answer 1

Step-by-step explanation:

Since AD bisects BC,

BD = DC.

Therefore 5x - 10 = 3x + 10 and x = 10.

Answer 2

Answer:

The value of x is 10.

Step-by-step explanation:

BD =CD

Which means

5x - 10 = 3x + 10

Let's solve.

$5x - 10 = 3x + 10 \\ \frac{ - 3x \: \: \: \: \: = - 3x \: \: \: \: \: }{2x - 10 = 10} \\ \\ 2x - 10 = 10 \\ \frac{ \: \: \: \: \: \: \: \: \: + 10 = + 10}{2x = 20} \\ \\ \frac{2x}{2} = \frac{20}{2} \\ \\ x = 10$

Therefore, x = 10.
