When 9 is subtracted from 5 times a number ,the result is 31
A number means an arbitrary variable, let's call it x.
5 times this number is written as 5x.
9 subtracted from this is written as 5x - 9
The result means we have an equation, so we set 5x - 9 = 31. This is our algebraic expression.
Now if we want to solve for x, we plug this equation into the search engine and get x = 8.
