If M is the midpoint of AB, AB = 6x + 40,
MB = 2x + 30, find x, AB, and MB.
x =
AB =
MB =

Not sure how to find x. I can manage finding AB and MB. If you could explain instead of just telling me the answer, that'd help me a lot!

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!
