9 less than 5 times a number is 3 more than 2x
The phrase a number means an arbitrary variable, let's call it x:
x
5 times a number means we multiply x by 5:
5x
9 less than 5x means we subtract 9 from 5x:
5x - 9
3 more than 2x means we add 3 to 2x:
2x + 3
The word is means an equation, so we set 5x - 9 equal to 2x + 3:
5x - 9 = 2x + 3 <-- This is our algebraic expression
If you want to solve for x, type this equation into the search engine, and we get:
x = 4
