Juliana,

In a system of equations word problem you want to locate the two totals that they give you. In this case: 23 ( the number of coins) and $4.70 ( the value)

Now build two equations based upon the totals

what gives us 23 coins? dimes added to quarters so d + q = 23

what gives us 4.70 10 cents per dime and 25 cents per quarter so .10d + .25q = 4.70

these are our two equations

Do you understand how to proceed from here?

What methods of solving systems of equations are you familiar with?

Yes but what does the question mean by “describe the meaning of the solution in terms of the original problem”?3d
