Answer:

Explanation:

It looks, by the markings, that ABC is equilateral.

That means that all three sides should be equal.

4x - 30 = 3x - 5 Subtract 3x from both sides

4x-3x - 30 = - 5 Combine

x - 30 = -5 Add 30 to both sides

x = - 5 + 30

x = 25

==============

To confirm, you need to involve BC

3x - 5 = 2x + 20 Subtract 2x from both sides

3x - 2x - 5 = 20 Add 5 to both sides

x = 20 + 5

x = 25

Conclusion: x = 25
