Hello. They gave you an expression for length MB. But you can write another expression for the same length.
The distance between points A and B is given as 6x+40, and point M is halfway between A and B. Does that hint give you an idea of how to write another expression for the distance from M to B?
Once you have different expressions for length MB, you may form an equation to solve for x.
Please share your attempt, if you would like more help. Thank you!
