Question 1144285
<br>
Let x be the units digit.<br>
Then, since the units digit is 2 more than the tens digit, the tens digit is x-2.<br>
The number itself is 10 times the tens digit, plus the units digit: 10(x-2)+x = 11x-20.<br>
The number, divided by 7 times the units digit, gives a quotient of 1 and a remainder of 4.  The means the number is 4 more than 7 times the units digit:<br>
{{{11x-20 = 7x+4}}}<br>
Solve using basic algebra.<br>
But finishing the problem is not the important thing for you.  What is important is to understand the part of the problem I showed -- the process of converting the given information into an equation that can be solved.
