Question 79317
Let x= cost of 1 lb walnuts
And y=cost of 1 lb almonds

Now we are told that:

3x+6y=$51--------------------------eq#1

We are also told that:

5x+4y=$55------------------------------eq#2

Multiply eq#1 by 5 and we get:

15x+30y=$255-------------------------New eq#1

Multiply eq#2 by 3 and we get:

15x+12y=$165------------------------New eq#2

Subtract new eq#1 from new eq#2 and we get:

18y=90  divide both sides by 18

y=$5.00------------------------------- cost of 1 lb of almonds


substitute $5.00 for y in eq #1

3x+30=51  subtract 30 froom both sides

3x=21  divide both sides by 3
x=$7.00-----------------------------------cost of 1 lb of walnuts

CK


3*$7+6*5=$51

$21+$30=$51
$51=$51
also

5*$7+4*$5=55

$35+$20=$55

$55=$55


Hope this helps----------------ptaylor
