To find the number that should be subtracted from 23 to get 16, you can set up a simple mathematical equation. Start by letting ‘x’ represent the number we want to find. The equation can be expressed as:
23 – x = 16
Now, to isolate ‘x’, you need to rearrange this equation. You can do this by subtracting 23 from both sides:
-x = 16 – 23
This simplifies to:
-x = -7
Next, if you multiply both sides of the equation by -1 to solve for ‘x’, you get:
x = 7
So, the number that should be subtracted from 23 to obtain 16 is 7.
