hello!

=============================================

First of all, let the number be u.

The product of 7 and u means you should multiply 7 times u:


\pmb{7u}

Now, subtract 4:


\pmb{7u-4}

This expression equals 17:


\pmb{7u-4=17}


\rule{200}{2}

[Now, let's Find the Value of u]

First, add 4 to both sides:


\pmb{7u=21}

Now, divide both sides by 7:


\pmb{u=3}

=======================================================

Hope everything is clear; if you need any clarification /explanation, kindly let me know, and I will comment and/or edit my answer :)
