C is the midpoint of AB. If AC = 2x + 18 and AB = 32, find x.

Answer:

x = -1

Step-by-step explanation:

What we know: AC+CB=AB (Because midpoints create two equal segments), and AC=CB

With this equation, we can substitute the AC and AB with what we were given.

2x+18+CB=32

Since AC=CB, we can put CB as 2x+18 as well.

So now our equation is:

2x+18+2x+18=32  or 2(2x+18)=32

Now, we just have to simplify!

4x+36=32

4x=-4

x = -1
