Given: A M = 4 x − 4 M B = 5 x + 2 A B = 25 Find: M B To determine

To find:

The value of MB.

Explanation

Given:

AM=4x4

MB=5x+2

And,

AB=25

The Figure (1) is given as,

Figure (1)

Approach:

The midpoint of a line is that separates the given line into two equal lengths or two equal segments.

According to addition property, if a point D lies in the between of an line AB, then
