solve for x

AB=24, MB=2x+4

Presumably M is the midpoint of AB.

AM+MB=AB
but
AM=MB
so,

2x+4 + 2x+4 = 24
4x=16
x=4

To solve for x in the given equation AB = 24 and MB = 2x + 4, we can set the expressions equal to each other and solve for x.

Since AB = MB in this case, we can equate the expressions:
2x + 4 = 24

To solve for x, we need to isolate x on one side of the equation. We can do this by subtracting 4 from both sides:
2x = 24 - 4
2x = 20

Next, divide both sides by 2 to solve for x:
x = 20 / 2
x = 10

Therefore, the solution to the equation is x = 10.
