Question 705956: My teacher just taught us this lesson, but I am still very confused on how to create the equations from the word problem. Here is the problem

We will solve this problem using system of LINEAR EQUATIONS:
......eq.1...where is number of dimes and is number of quarters
....eq.2
________________________
First, we solve eq.1 for :
......eq.1
........eq.1a
Then, we substitute the solution for in eq.2:
....eq.2
.......solve for ......the number of quarters
Now that we know how much quarters there are, we can complete the equation eq.1a and solve it for :
........eq.1a
......the number of dimes
