<h3>How to Write an Algebraic Expression?</h3>
Let the unknown number be represented as x.
The word "difference" means subtraction which is "-". Multiplied means times.
We would have the following:
"Difference of x and 1" is: x - 1
x - 1 multiplied by 7 would be: 7(x - 1)
Therefore, the algebraic expression is: 7(x - 1).
