<PRE><B>Question 536876</B>
d is dimes. q is quarters.&lt;P&gt;
d+q=86.&lt;P&gt;
.1d +.25q = 14.60&lt;P&gt;
Use the first equation to find d in terms of q.&lt;P&gt;
d+q = 86&lt;P&gt;
Subtract q from both sides.&lt;P&gt;
d=86-q&lt;P&gt;
Substitute that d value into the second equation.&lt;P&gt;
.1(86-q) + .25q = 14.6&lt;P&gt;
Multiply .1 by both terms in the ().&lt;P&gt;
8.6 - .1q +.25q = 14.6&lt;P&gt;
Combine the q&#39;s, subtract 8.6 from both sides.&lt;P&gt;
.15q = 6&lt;P&gt;
Divide both sides by .15&lt;P&gt;
q=40&lt;P&gt;
d = 86 - q = 86 - 40 = 46
