Question 670863
x y and z for how many nickels dimes and quarters


"A bank contains 44 coins"
{{{x+y+z=44}}}


"twice as many dimes as nickles"
{{{y=2x}}}


"8 fewer nickles than quarters. "
{{{z-x=8}}}


You have enough to write the total coin equation as one single variable.
{{{x+2x+(x+8)=44}}}
{{{4x=44-8}}}
{{{x=11-2}}}
{{{x=9}}}-------------------With this variable (for the nickels) you can now find the dime and quarter counts, and find how much money.
