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
Hope this helped!
