**DW**, Saturday, April 20, 2013 at 6:23pmpretend $1 is x

and $5 is y

x+8=y *bc you have to add 8 $1 to

have the same number of $1 as $5

1x+5y=124 *this is basically saying that there is an "x" number of $1 bill plus a "y" number of $5 will get u $124

now use elimination:

since y=x+8 plug "x+8" as "y" in the other equation

1x+5(x+8)=124

1x+5x+40=124 *distribute

6x=84

x=14

now plug "x" into the first equation to find y:

x+8=y

14+8=y

y=22

this means that 14 $1 and 22 $5 will get you $124

now check your answer:

14+8=22 *correct

and

1(14)+5(22)=124 *correct
