    decreased means subtract `is` mean equal sign now just translate into math equation

    they said `number` we don't know what number is that so that's why we would use x as a number any variable

    you could write in "A number" instead of "x" but people use short names in algebra

    in fact when I see x-10=2*x I read that as "a number decreased by 10 is 2 times that number"

    you just have to write the equation to find x value you can solve that equation for x after that you can substitute x for its value to check ur answer.
