If you subtract a number from 30, that is 30-x. Double that, and you can get 2[30-x] because you want to know what the number, x, subtracted from 30 is first before doubling it or multiplying it by two. Then, you can turn it into an equation and solve it. 2[30-x]=48 because the question stated that twice of 30-x equals 48. You can solve it using the Distributive Property and distributing the number 2 to 30 and x, receiving 60-2x=48. Afterwards, simply subtract 60 from both sides [you receive -2x=-12]. Finally, you divide both sides by -2 and get 6,

Subtract 30 and 6 which equals 24.Then you double 24 and you get 48 :)

2(30-x)=48
30-x=24
x=6
