Half of the books you own are mysteries. one third are historical fiction. the four are science fiction. how many mysteries are there? (please explain)

x=1

Step-by-step explanation:

First we make our equation. Half the books so 1/2 and then 1/3 and 4. So first off they are all postive ( we cant have negative books) and to make the equation we need to find how many books are all together. So 1/2+1/3+4. First combine like terms 1/2+1/3=3/4 then add 3/4 to 4 which is the same as 3/4+4/1= 4 3/4.

Let's solve your equation step-by-step.
