The toughest part of this is to figure out exactly how to express that complex formula description.
You begin by writing the equation form as it is in written in English, the important words there are the 'whole' ones... which means to close the parenthesis.
Once you have written it all out as shown on the first line of the attached image, you just have to do the calculations, as demonstrated in the other 3 lines.

This is a problem of system of linear equations in two variables. This concept of mathematics is very useful in real-life problems. You can solve a system by finding the solution. A solution of a system are the values of the variables that satisfies each equation in the system. So by knowing these concepts we can get a system of equation by analyzing each statement step by step, that is:
1. Alice has a total of 12 dimes and nickels.
Let the variables:
1st. Equation:
<span>2. She has 2 more nickels than dimes
2nd Equation:
Therefore our system of linear equations is:
</span>
Conclusion:
<span>Alice has 5 dimes and 7 nickels. </span>
