Translate the statements into equations. We can use 'x' for dimes and 'y' for quarters.
"<span>A boy has 11 coins in dimes and quarters"
"</span><span>Their value is $1.70"
</span>
<span>
To solve this, we can first solve for one of the variables in the first equation, and then plug that into the second equation:
Subtract 'x' to both sides:
Now plug this value of 'y' into the second equation:
</span>
So this equation could be used to solve the problem.
